void pointer and Casting

Code

#include <stdio.h>

void add_and_print(void *a, void *b, char type) {
    switch (type) {
        case 'i': 
            printf("%d", *((int*)a) + *((int*)b));
            break;
        case 'f':
            printf("%.1f", *((float*)a) + *((float*)b));
            break;
        default:
            printf("Unknown type: %c", type);
            break;
    }

}

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;
