C 替换打印文本

Question

So I have this script and I want to replace printed "Dont" with "Lets". I don't want to use system() since the effect is different.

#include <stdio.h>

int main(){
    printf("Dont do this");
    /* Replace printed "Dont" with "Lets" */
    return 0; 
}

Answer 1

Try \r :

#include <stdio.h>

int main(){
    printf("Dont do this");
    printf("\rLets");
    printf("\n");
    return 0; 
}
