// Example of using if() with && and ||


 int main(){
»  int j=2, k=3;
»  double x=4.1;

  // LHS is true so RHS is NOT evaluated
»  if (j+k>x||x>10) 
    printf("Hello 1\n");

  // LHS is true so RHS IS evaluated (but is false)
»  if (j+k>x&&x>10) 
    printf("Hello 2\n");

  // Combining && and ||
»  if ((j+k<x&&x>10)||j<k) 
    printf("Hello 3\n");
