Problem Statement

Write a C program using an enum representing operations (ADD=1, SUB=2, MUL=3, DIV=4) to compute expressions.

Input Format

Operation code (1-4) followed by two integers A and B.

Output Format

Print the calculation result.

Constraints

1 <= Op <= 4, -1000 <= A, B <= 1000

Sample Input

1 10 20

Sample Output

Explanation

Operation 1 (ADD) on 10 and 20 gives 30.

Starter Code

#include <stdio.h>

enum Operation { ADD = 1, SUB, MUL, DIV };

int main() {
    int op, a, b;
    if (scanf("%d %d %d", &op, &a, &b) == 3) {
        // Write your code here
    }
    return 0;
}
