  int main(void)
  {
      //
      // If you want to use more than one condition, you
      // can use if else-if statement. The syntax of the
      // if else if statement is as follows:
      //
      // if (condition-1)
      // {
      //     /* code block if condition-1 is true */
      // }
      // else if (condition-2)
      // {
      //     /* code block if condition-2 is true */
      // }
      // else if (condition-3)
      // {
      //     /* code block if condition-3 is true */
      // }
      // else
      // {
      //     /* code block all conditions above are false */
      // }
      //
      // The else-if statement is used to make multiway decisions.
      // The conditions in the corresponding if and else if branch
      // evaluates in sequence from top to bottom. If a condition
      // evaluates to true, the statements associated with it executes
      // and terminates the whole chain.
      //
      // You can have as many branches as you want but it is not
      // recommended because the code looks less readable and difficult
      // to maintain.
      //
      // The following example compares the input number with zero (0)
      // and displays the corresponding message:
      //
      int x;
      printf("%s", "Please enter a number: ");
      scanf("%d", &x);
  
      if (x > 0)
      {
          printf("%d > 0", x);
      }
      else if (x < 0)
      {
          printf("%d < 0", x);
      }
      else
      {
          puts("zero");
      }
      return EXIT_SUCCESS;
  } // end of function main
