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.
Steps
- 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.

In conclusion, the clrscr() function in the C programming language is used to clear the contents of the console screen or output panel. It is commonly used to remove any previous output and provide a clean and blank canvas for new program outputs or user interactions. This function is particularly useful in projects where frequent screen updates or user interface interactions are required.
To clear the screen using clrscr() function, a programmer needs to include the conio.h header file in their program. After that, they can call clrscr() whenever they want to clear the console screen or output panel. This function essentially fills the entire screen with blank spaces, effectively erasing any previous output.
Clearing the screen can be useful in a variety of programming scenarios. For instance, it can enhance the readability and user experience by removing cluttered or irrelevant information from the screen. It can also be used to create dynamic interfaces where the screen gets updated with new information frequently.
Overall, the clrscr() function is a simple yet powerful tool in C programming, enabling programmers to create cleaner and more efficient user interfaces. Understanding how to clear the panel and screen using this function is essential for creating visually appealing and interactive programs.
