void pointer and Casting

Code

#include <stdio.h>

void add_and_print(void *a, void *b, char type) {
    if (type == 'i') {
        printf("%d", (*(int *)(a)) + (*(int *)(b)));
    } else if (type == 'f') {
        printf("%0.1f", (*(float *)(a)) + (*(float *)(b)));
    } else {
        // Do nothing
    }
}

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;
