#include <stdio.h>

int main() {

    char op;ca

    double num1, num2;

    printf("Enter operator (+, -, *, /): ");

    scanf(" %c", &op);

    printf("Enter two operands: ");

    scanf("%lf %lf", &num1, &num2);

    switch(op) {

        case '+':

            printf("%.2lf\n", num1 + num2);

            break;

        case '-':

            printf("%.2lf\n", num1 - num2);

            break;

        case '*':

            printf("%.2lf\n", num1 * num2);

            break;

        case '/':

            if (num2 != 0)

                printf("%.2lf\n", num1 / num2);

            else

                printf("Error! Division by zero.\n");

            break;

        default:

            printf("Invalid operator\n");

    }

    return 0;
