C program to illustrate goto statement

Write a C program to illustrate goto statement.

  #include <stdio.h>

  int main() {
        int num1, num2, ch, res;

        /* get the input values from the user */
        printf("Enter your input for num1 and num2:");
        scanf("%d%d", &num1, &num2);

        /* get the user choice */
        printf("1. Addition, subtraction, multiplication\n");
        printf("2. Multiplication alone\nEnter your choice:");
        scanf("%d", &ch);

        /* if the choice is 2, then execute instructions from divide */
        if (ch == 2)
                goto divide;

        /* Addition of two numbers */
        res = num1 + num2;
        printf("Addition Result(%d + %d): %d\n", num1, num2, res);

        /* Addition of two numbers */
        res = num1 - num2;
        printf("Subtraction Result(%d - %d): %d\n", num1, num2, res);

  divide:
        /* Multiplication of two numbers */
        res = num1 * num2;
        printf("Multiplication Result(%d X %d): %d\n", num1, num2, res);
        return 0;
  }

  Output:

  jp@jp-VirtualBox:~/$ ./a.out
  Enter your input for num1 and num2:100 10
  1. Addition, subtraction, multiplication
  2. Multiplication alone
  Enter your choice:2
  Multiplication Result(100 X 10): 1000

  jp@jp-VirtualBox:~/$ ./a.out
  Enter your input for num1 and num2:30 10
  1. Addition, subtraction, multiplication
  2. Multiplication alone
  Enter your choice:1
  Addition Result(30 + 10): 40
  Subtraction Result(30 - 10): 20
  Multiplication Result(30 X 10): 300
