C++: Why use it?

C++: Why use it?

C++ is one of the most widely used programming languages in the world.

C++ is a component of operating systems, embedded systems, and Graphical User Interfaces.

C++ is an object-oriented programming language that allows for code reuse and reduces development costs.

C++ can be portable and used to create applications adapted for multiple platforms.

C++ is easy and fun to learn!

C++ is very close to C, C#, and Java. This makes it simple for programmers to switch from C to C++ or vice versa.

C++ has many uses. C++ can interface with almost every programming language, and nearly all systems can compile and run code in C++

  • It provides great performance.
  • C++ combines both high-level and low-level features.The MongoDB database was written in this programming language.

A study conducted in 2024 found that over 2,500 software engineers globally list C++ as one of their top three major languages.

Software Developers love this language because it allows them to control their code. C++ offers almost all the Key features an experienced developer would want: multiple inheritances, templates, and operator overloading.

Difference Between C and C++

Difference Between C and C++

C++ was created as an extension to C. Both languages have nearly the same syntax.

C++ and C++ have two main differences: C++ supports classes and objects, while C++ does not.

C++ developers specialize in writing code in the C++ programming language. They can create and design modern software for many different uses by understanding the language's intricacies.

C++ can be used to develop mobile and software applications. It is driven by the client's or employer's requirements.

C++ developers use C++ to create enterprise-grade software and apps. C++ is widely utilized for its many benefits, such as portability on devices around the globe, high memory and performance optimization, and its ability to scale for tasks that rely upon such functionality.

C++ developers are software engineers who can create various applications using the C++ programming language. They are also capable of maintaining any C++-based program they make.

C++ is a general-purpose language that allows for many different types of applications. C++ developers will build mobile applications just as much as desktop applications.

C++ can be used for system programming, closest to desktop applications. C++ is perfect for embedded software, such as digital watches and pacemakers.

C++ developers need to understand how hardware and software interact.

C++ developers can do much more than just code. Best C++ developers can also organize and conceptualize app ideas.

This can also include the creation of complex algorithms.

C++ developers also have expertise in object-oriented programming.

C++ has Many Advantages

C++ can bring many benefits to your business. C++ is an intentionally designed programming language that developers love.

Portability

C++ is highly portable because it can be used on many different systems. Mobile apps are especially attracted to this feature.

C++ allows multi-platform development and can help developers resolve the long-running battle between native and cross-platform apps.

Object-oriented

C++'s object-oriented additional features include inheritance, polymorphism, and abstraction.

  • Inheritance allows you to derive a class using the same methods and attributes as another class.
  • Polymorphism refers to when a parent (which you might consider as a set) can reference a child or subset.
  • Encapsulation is where data and code are linked together.
  • Abstraction is when the user is omitted from unnecessary information.

Middle-level

C++ is a middle-level programming language. It can be used to build drivers, kernels, and low-level programming.

It can also be used to build software applications or high-level programming.

General-purpose

C++ is one of the universal languages available. It can be used to create graphics, games, and calculators.

Rich Library

C++ comes with a wealth of functions built in. These functions can manipulate files, data structures, and methods.

Modern C++ Best Practices For Error Handling And Exceptions

Modern C++ Best Practices For Error Handling And Exceptions

Modern C++ uses exceptions to handle logic and runtime errors in almost all cases. This is especially true when there are multiple function calls in the stack between the function that detects a mistake and the process that handles it.

The exceptions allow code that detects errors and passes the information up to the call stack in a well-defined, formal way.

For unique codes, make exceptions.

Programming errors can be divided into logic errors, which are caused by programming errors, such as an "index out of range" error.

Runtime errors that are not under the programmer's control, such as a "network services unavailable" error, can also occur.

C-style programming or COM error reporting can be done by either returning an error code or status code for a function or setting a global variable that the caller may retrieve after each function call to determine if errors were reported.

Modern C++ prefers exceptions for the following reasons.

  • A call to code must recognize an error condition to handle it.Program execution is stopped if an exception is not addressed.
  • An exception jumps to the correct point on the call stack.Intermediate functions can propagate the exception.They can be coordinated with other layers.
  • After an exception is thrown according to defined rules, the exception stack-unwinding system destroys all objects within its scope.
  • An exception allows for a clear separation between the code that detects and the code that deals with the error.

Performance Exceptions

Performance Exceptions

If no exception is thrown, the exception mechanism incurs a very low-performance cost. The cost of stack traversal and unwinding if an exception is thrown is approximately the same as a function call.

Additional data structures must be created after a block has been entered to track the stack. Further instructions will also need to be given to unwinding the stack in case of an exception.

In most cases, however, the impact on performance and memory footprint is insignificant.

Only memory-constrained systems are likely to suffer from the adverse effects of exceptions on performance. Performance-critical loops are those where errors are likely to occur frequently, and tight coupling exists between the code to fix them and the code that reports them.

It is possible to determine the actual cost by measuring and profiling exceptions. Even in rare instances where the price is high, it's possible to weigh that against the benefits of a well-designed exception policy.

Exceptions and Assertions

Exceptions and Assertions

Two distinct mechanisms can be used to detect runtime errors in programs: asserts and exceptions. To test for conditions in development, use assert statements.

This is even if your code is accurate. It's not a good idea to handle an error like this by creating an exception.

This is because it indicates that there are problems in your code.

This error does not mean a condition that the program must recover from at runtime. A assert halts execution at the statement to allow you to inspect the program state using the debugger.

An exception continues execution starting at the appropriate catch handler. You can use exceptions to verify errors that may occur during runtime, even if your code works correctly.

These conditions can be handled by exceptions, even if recovery outputs nothing but a message to the log and ends your program.

Use exceptions to verify arguments to public functions. Even if your process is error-free, you may only be able to control some arguments passed to it by users.

After many years of C++ developers using exception handling, exception handling was finally added to C++.

A software developer with a focus on the C++ coding language is known as dedicated C++ developers.

C++ Exceptions

C++ Exceptions

Different errors can occur when executing C++ code: programming, input, and other unforeseeable errors.

C++ will usually stop when an error occurs and display an error message. C++ will throw an error (throw an exception).

C++ has had exceptions since the early 1990s. The standard approves them as a mechanism for writing fault-tolerant code in the language.

But, developers often choose to refrain from using exceptions for many reasons. Among those quoted are Raymond Chen's article Cleaner and More Elegant and Google C++ CSS Style Guide.

Instead of taking sides in the debate, I want to offer a balanced perspective on the pros and cons of exceptions.

This article does not aim to convince readers to use error codes or exceptions but to help them make informed decisions that are best for their project.

The report is a combination of six arguments in favor of exceptions and six against that which can be heard often in the C++ community.

Arguments to use Exceptions

Exceptions are a way to separate error-handling code and normal program flow. This makes the code easier to read, more robust, and more extensible.

These exceptions can be costly and violate the promise that we will only pay for what we use.

A developer should measure the impact of language key features or libraries on performance and determine if the effect is acceptable for their situation.

This advice can be challenging to follow when dealing with exceptions. The performance of an exception-handling mechanism depends on its implementation.

Therefore, conclusions based upon measurements made with one compiler might not hold if the code is ported to another compiler or another version of the compiler.

It is challenging to add exceptions to legacy code.

This means that exception safety should never be considered an afterthought. It is better to write code without thinking of exceptions.

This reminds me of how to make a thread-safe code if it needs to be registered with thread safety in mind.

It is not only tricky to check the code for possible problems, but it is also hard to test it. If the code base has modularity, it's possible to write new code compatible with the existing code.

Defining the boundaries and ensuring exceptions do not cross them is essential.

C++ Exception Handling

C++ Exception Handling

C++ has Exception Handling as a significant advantage over C. Exceptions refer to runtime anomalies and abnormal conditions a program encounters during execution.

There are two types: a) Synchronous and b) Asynchronous.

These exceptions are outside the program's control, such as keyboard interrupts or disc failure. For this purpose, C++ has the following particular keywords:

Catch: A block of code executed when a specific exception is thrown.

Throw: Used to throw an error. Also used to list exceptions that a function throws but doesn't handle.

Grouping Error Types Both basic types and objects are possibly to be used as exceptions in C++. You can create a hierarchy from exception objects, group them in namespaces and classes, and then categorize them according to their type.

Why Exception handling?

These are the main benefits of exception handling over traditional error management: Separation of Error Handling code From Normal Code: In traditional error handling codes, you always have if-else conditions for handling errors.

These conditions, along with the code to handle errors, get mixed up in the normal flow. This makes it less readable and more difficult to maintain. The code to handle errors is now separate from the normal flow.

Methods/Functions can only handle the exceptions they choose. A function may throw many exceptions but choose to handle some.

Other exceptions that are thrown but not caught may be handled by the caller. If they are not caught, the caller can handle the exceptions. A function in C++ can use the throw keyword to specify which exceptions it throws.

This function's caller must deal with the exception in some manner (either by catching it or identifying it again).

Exception handling in C++

This is an example of C++ exception handling. The program output explains how try/catch blocks are executed. There's a catch block called the "catch-all" block.

It can catch all kinds of exceptions. The catch (...) will be executed if an int is thrown in the exception. Implicit type conversion doesn't happen for primitive types.

The program will terminate abnormally if an exception is made and it is not caught. An exception of the derived class should be caught before an exception of the base class.

Since C++11, Dynamic Exception Specification is no longer supported. It can cause your program to abort randomly, which could be one reason.

If you throw an exception that is not in the dynamic exception specification, this can occur. The program will abort because it calls terminate() (indirectly), which defaults to abort(). All objects within the enclosing try blocks are destroyed when an exception is made.

The control is then transferred to the catch block.

Conclusion

The good news is that compilers get better at producing efficient code even in the presence of exceptions. Exceptions will have less impact on the performance of your code in the future.

If your development process is well-organized and you follow code standards, writing modern-style C++ code that relies upon clearing up resources may be a good idea.

However, exceptions are best used when your code base can be modular. You should not use exceptions if your code is not safe, if there is a lack of discipline within your development team, or if the system you are creating is complex and real-time systems.
