void pointer and Casting

Code

#include <stdio.h>

void add_and_print(void *a, void *b, char type) {
    switch(type)
    {
        case 'i': {
            int *ptr1 = (int*) a;
            int *ptr2 = (int*) b;
            printf("%d", *ptr1 + *ptr2);
        } break;

        case 'f': {
            float *ptr1 = (float*) a;
            float *ptr2 = (float*) b;
            printf("%.1f", *ptr1 + *ptr2);
        } 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;
}
