C Program to Create a Calculator using Switch Statement.

In this C programming tutorial, we are going to learn how to create a simple calculator to perform simple arithmetic calculations like +, - x, and / between two operands given by the user. Here we are going to use the switch statement to create our basic calculator.

Calculator using Switch statement in C program.

//C calculator using switch statement
#include <stdio.h>

int main() {
    char operator;
    double num1, num2, result;

    // Input the operator and two numbers
    printf("Enter an operator (+, -, *, /): ");
    scanf("%c", &operator);

    printf("Enter two numbers: ");
    scanf("%lf %lf", &num1, &num2);

    // Perform the calculation based on the operator
    switch (operator) {
        case '+':
            result = num1 + num2;
            printf("Result: %lf\n", result);
            break;
        case '-':
            result = num1 - num2;
            printf("Result: %lf\n", result);
            break;
        case '*':
            result = num1 * num2;
            printf("Result: %lf\n", result);
            break;
        case '/':
            result = num1 / num2;
            printf("Result: %lf\n", result);
            break;
        default:
            printf("Error: Invalid operator.\n");
    }

    return 0;
}

Output:

Enter an operator (+, -, *, /): +
Enter two numbers: 23 12
Result: 35.000000

Output:

Enter an operator (+, -, *, /): %
Enter two numbers: 23 43
ERROR!
Error: Invalid operator.

Explanation:

In this program, the user is prompted to enter an operator (+, -, *, /) and two numbers. Then, using the switch statement, the program performs the corresponding calculation based on the operator.
