How can terminate input when input specifed char?

I wanna do this

Code:

---

char chr[10];
while (scanf("%s", chr) != 'x') {
      ...........
}

---

Means the prog is terminated in the following input data.

Code:

---

0001
1003
0206
0034
1111
1003
x      <------ When I input 'x', the program stop

---

the while code doesn't work...... How can I implement this action?

Code:

---

while(fgets(chr,10,stdin) != NULL)
{
  if(chr[0] == 'x')
      break;
  //do something
}

---

Code:

---

char chr[10];
while (scanf("%s", chr) != 'x') {
      ...........
}

---

More this will not work. in fact. Scanf returns no of arguments read from the used. Avoid using scanf. You could do something like this if your want

Code:

---


    while((ch=getchar() != 'x') && ch != 'X');
   
    printf("You are out\n");

You never need to typecast chars to ints.

Quzah true, but for some reason when i wrote that code, it wasn't getting the ASCII value of X. That the reason when type casted it on purpose.

Any code updated
