How do i get this to properly exit the program?

So i am trying to get this program to simply exit but i can seem to get it to work.

i tried a lot of things. one thing i found odd as well is if i made x = 0 in the while loop it would immediately exit the program so i had to make it x !=0. i dont understand what that is so if you can answer that as well that would be nice.

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main()
{
    char a[256];
    int x = 0;
    while (x != 0) {
        int y = strcmp(fgets(a, 256, stdin), "exit");
        if (y==0) {
            exit(0);
        }
        else {
            printf("Line read:%s\n",a);
        }
    }
    return 0;
}

so it should output right now something like this(i am also running this in a linux terminal):

//input://
 hello
//output:// 
 Line read: hello
//(program stays open for more inputs)//
//input//
 exit
//(the program now closes in the terminal and you return to directory)//

The keyboard input contains a new line at the end. Change "exit" to "exit\n" in call to strcmp.
