Question

I need that my program shows the output using commas as decimal separator.

According to this link: http://www.java2s.com/Code/Java/Development-Class/Floatingpointwithcommasf.htm you can use in Java something like this:

System.out.printf("Floating-point with commas: %,f\n", 1234567.123);

Is there a flag or something that I can use to have a similar behaviour in C?

Thanks in advance!

If you want, you can set current locale at the beginning of your program:

#include <stdio.h>
#include <locale.h>


int main()
{
    setlocale(LC_NUMERIC, "French_Canada.1252"); // ".OCP" if you want to use system settings
    printf("%f\n", 3.14543);
    return 0;
}
