Thread: Easy code question

So, I wrote this:

Code:

 
#include <stdio.h>
#include <ctype.h>

int main() {
    char m;
    while(m=getchar() !='\n') {
              if(isdigit(m))  printf("There is a number in line");
    }

}

I thought this will go char by char and check if any char is a digit in line. So Im wondering why it doesnt work?
