how can I clear the screen. clrscr () does not work.

Question

#include <stdio.h>
#include <stdlib.h>

int main()
{
    printf("Hello World errado");
    clrscr();
    printf("Hello World correto");

    return 0;
}

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include<conio.h>      // clrscr() requires a header file of conio.h

int main()
{
    printf("Hello World errado");
    system("clear");           // if you are using GCC compiler / online compilers, use this instead of clrscr()
    clrscr();                    // if you are compiling on Turbo C++ compiler

    printf("Hello World correto");
    getch();
}

Answer 2

Add #include<conio.h> header file and try it.

Answer 3

the clrscr() function is in the conio.h library but that library isn't working with this compiler for some reason.  Therefor you can include the code for that function in your program yourself.

#include <stdio.h>
#include <stdlib.h>
//#include "conio.h"

void clrscr()
{
       printf("\x1b[2J");
}

int main()
{
    printf("Hello World errado");
    clrscr();
    printf("Hello World correto");

    return 0;
}
