Thread: Why wont this simple calculator program using the switch function work?

Code:

/*program to evaluate simple expresion of the form
value operator value*/


#include <stdio.h>


int main(void)
{
    float value1, value2;
    char operator;


    printf("Type in your expression.\n");
    scanf("%f %c % f", &value1, &operator, &value2);


    switch (operator)
    {
        case '+':
            printf("%.2f\n", value1 + value2);
            break;
        case '-':
            printf("%.2f\n", value1 - value2);
            break;
        case '*':
            printf("%.2f\n", value1 * value2);
            break;
        case '/':
            if (value2 == 0)
                printf("Division by zero\n");
            else
                printf("%.2f\n", value1 / value2);
            break;
        default:
            printf("Unknown operator\n");
            break;
    }


    return 0;
}
