Question

#include <stdio.h>

int force(int mass, int acce);

int main ()
{
    int mass;
    int acce;

    scanf( "%d", &mass );
    scanf( "%d", &acce );
    printf("The force is %d n\ ",force(mass ,acce));
}

int force(int mass, int acce)
{
    return mass * acce;
}

I am trying to run a simple program in C. When I run the above program I find the following error:

Force.c:12:11: warning: unknown escape sequence: '\040'.

The is not clear to me. Would you please give an explanation.

Answer 1

You put n\ in your printf statement. I think you meant \n. This is called an escape character (this one is a newline). Yours was trying to do the escape character '\ '. If you want to print a single backslash, use \\.
