In the world of C programming language, the clrscr() function holds a significant place when it comes to clearing the panel and screen. As the name suggests, clrscr() is short for “clear screen.” It is a function that allows programmers to swiftly remove all the existing content from the screen, creating a blank canvas for subsequent operations.
By using clrscr(), developers can avoid cluttered and messy displays to ensure a more organized and user-friendly interface. This function is primarily used in console applications where a clean and uncluttered screen is required, enabling users to have a seamless and visually appealing experience.
While there are multiple ways to achieve screen clearance, the clrscr() function is particularly useful due to its simplicity and ease of implementation. In this article, we will delve deeper into understanding the clrscr() function and explore how to effectively utilize it to clear panels and screens in the C programming language.

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.
