Clear screen in C and C++ on UNIX-based system?

Question

I want to know: how to clean screen on an UNIX-based system? I searched on the Internet, but I\'ve just found how to do it on Windows: system(\"CLS\") I don\'t want exactly

Answer 1

It is usually not a matter of just clearing the screen, but of making a terminal aware application.

You should use the ncurses library and read the NCURSES programming HowTo

^{(You could perhaps use some ANSI escape codes as David RF answered, but I don't think it is a good idea)}

Answer 2

This code is for clear screen with reset scrollbar position in terminal style windows

#include <iostream>

int main(){
   std::cout << "\033c";
   return 0;
}

Answer 3

You can use the following code which use termcap for clear screen. (don't forget to link with the library)

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

void clear_screen()
{
char buf[1024];
char *str;

tgetent(buf, getenv("TERM"));
str = tgetstr("cl", NULL);
fputs(str, stdout);
} 

Answer 4

Maybe you can make use of escape codes

#include <stdio.h>

#define clear() printf("\033[H\033[J")

int main(void)
{
    clear();
    return 0;
}

But keep in mind that this method is not compatible with all terminals

Answer 5

Use system("clear"); with header #include <stdlib.h> (for C Language) or #include <cstdlib> (for C++).

Answer 6

#include <stdlib.h>
int main(void)
{
    system("clear");
}
