void pointer and Casting

Code

#include <stdio.h>

void add_and_print(void *a, void *b, char type) {
    switch(type)
    {
       case 'i':
        {
            int result = *(int*)a + *(int*)b;
            printf("%d\n", result);
        } break;

        case 'f':
        {
            float result = *(float*)a + *(float*)b;
            printf("%0.1f\n", result);
        } break;
        default:
        printf("unsupported type");
    }
}

int main() {
    char type;
    scanf(" %c", &type);

    if (type == 'i') {
        int x, y;
        scanf("%d %d", &x, &y);
        add_and_print(&x, &y, type);
    } else if (type == 'f') {
        float x, y;
        scanf("%f %f", &x, &y);
        add_and_print(&x, &y, type);
    }

    return 0;
