How to clear screen in C Language

We can clear screen in C language according to the compiler.

1. Using clrscr() - For TurboC Compiler
2. Using system("cls") - For gcc/g++ & TurboC Compiler windows
3. Using system("clear") - For gcc/g++ compiler in Linux

/* TurboC Compiler */ #include <stdio.h> #include <conio.h> /*for clrscr()*/ int main(){ int num=100; /*Use after declaration section*/ clrscr(); /*clear output screen*/ printf("value of num: %d\n",num); return 0; } /* GCC compiler and TurboC Compiler For Windows */ #include <stdio.h> #include <stdlib.h> /*for system()*/ int main(){ int num=100; /*Use after declaration section*/ printf("Not display due to clearscr"); system("cls"); /*clear output screen*/ printf("value of num: %d\n",num); return 0; } /* gcc/g++ compiler Linux */ #include <stdio.h> #include <stdlib.h> /*for system()*/ int main(){ int num=100; /*Use after declaration section*/ system("clear"); /*clear output screen*/ printf("value of num: %d\n",num); return 0; }
