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

You can achieve this using CSI sequences:

#include 
int main()
{
    printf("\x1b[H\x1b[J");
}

What does \x1b[H?

Actually it is the same as \x1b[1;1;H, it means that it will move the cursor to row 1 and column 1.

What does \x1b[J a.k.a \x1b[0;J?

If n is 0 or missing, it will clear from cursor to end of screen.
