#include <stdio.h>

int main(int argc, char** argv)
{
  printf("sizeof(int)=%d, sizeof(long)=%d, sizeof(long long)=%d\n", sizeof(int), sizeof(long), sizeof(long long));
  long long check[3];
  check[0]=1;
  printf("x1=%d, x2=%d, x3=%d\n", check[0],check[0],check[0]);
  return 0;
}

$ gcc x.c 
$ ./a.out 
sizeof(int)=4, sizeof(long)=4, sizeof(long long)=8
x1=1, x2=0, x3=1
