Should You Avoid the `system()` Function in C and C  ?

Avoidance of system() Function in C and C

Despite its prevalence, the system() function should be carefully considered in C and C programming. Here are the reasons why it's advisable to avoid system():

Cross-Platform Dependency:
The system() function invokes external programs, which can vary depending on the operating system. For instance, the command system("cls") may work on Windows but is not supported on Linux. This platform dependency can lead to cross-platform compatibility issues.

Performance Overhead:
System() spawns a new child process to execute the external program, introducing performance overhead. This is particularly noticeable compared to inline code, which executes directly within the current program.

Alternatives for Screen Clearing:
Since the clrscr() function is not available in CodeBlocks, alternative methods can be used to clear the screen without using system(). Here are a few options:

  • Windows:

    • std::cout << "
