Thread: why doesn't this work?

Code:

#include <stdio.h>

int main()
{
    char c[] = "0110";
    if (c == "0110")
        printf("%s", c);

    return 0;
}

Char c [] is an array of characters, initialize it's size: char c [3].

Or for the exact answer to your question, putting a string into char c [] puts it in read only format, so you can't output a value that is read only, it also has to be able to write the value (so initialize the size of the char array), see: string - What is the difference between char s[] and char *s in C? - Stack Overflow

This is the correct issue; ignore the first two posts by Terrance.
