What is clrscr() function in C programming language and how to clear panel and screen in C

The clrscr() function is used to clear the MS-DOS console screen on older C programming language compilers such as Turbo C and Turbo C++. clrscr() is not a standard C function, so if you compile a program that includes the clrscr() function on a modern compiler like GCC or Clang, you will get a “function not declared” error ( undeclared function) or “not declared in this scope.” So what do you need to do when you want to remove the console from your program? clrscr() with the system() function used to clear the screen in C programming language.

Add the stdlib.h header file to the code. The system() function is used to pass commands to the terminal or console. This function is declared in the stdlib.h header file. ^{[1] X Research Source}

The clrscr() function is defined in the conio.h header file. We’ll remove the clrscr() function and replace it with system() , so you can delete the conio.h header file.

Replace the clrscr() function with system("cls") on Windows. The cls command clears the console screen when executed on the Windows command prompt. The cls command when passed through the system() function clears the screen very effectively.

Replace the clrscr() function with system("clear") on Linux or macOS. The system() function will pass the clear command to the console. The Linux (as well as macOS) command to clear the console is clear , so the system("clear") function clears the console window. ^{[2] X Research Source}
