I need help for using if and else functions in C Programming.

Question

I am sure this program is ok but and dose not WORK.


#include <stdio.h>
int main (){
int x,y,z;
printf("please enter value of x");
scanf("%d",&x);
printf("please enter value of y");
scanf("%d",&y);
if (y == 0) {
printf("You can not divide by zero");}
else{
z = x / y;
printf("divide = %d \n",z);}

and also 

#include <stdio.h>

int main (){

int x,y,z;

printf("please enter value of x");

scanf("%d",&x);

printf("please enter value of y");

scanf("%d",&y);

if (y != 0) {

z = x / y;

printf("Divide = %d \n",z);

}

else{

printf("You can not divide by zero");

}
