gotoxy() function substitute for Dev C not working

I was looking for a substitute of gotoxy for Dev C++ v5.11 (gcc compiler) and found this:

void gotoxy(int x,int y) {
    printf("%c[%d;%df", 0x1b, y, x);
}

After this when I tried to call this function as follows:

int main() {
    gotoxy(20, 10);
    printf("Hello");
    return 0;
}

Output was not as expected:

<-[10;20fHello

This was printed in top left most corner of screen (i.e. 1,1) instead of (20,10).

Please give me suggestions that what I can do to use gotoxy in my code.

Your ANSI escape sequence is incorrect, it should be \033[%d;%dH, but it seems your terminal does not support ANSI VT100 escape sequences at all. In Windows, there might be a configuration setting to enable it, VT100 emulation is standard in most modern operating systems terminals (unix, linux, BSD, OS/X...).

Here is the modified code:

#include <stdio.h>

void gotoxy(int x, int y) {
    printf("\033[%d;%dH", y, x);
}

int main(void) {
    gotoxy(20, 10);
    printf("Hello\n");
    return 0;
}
