void pointer and Casting

Code

#include <stdio.h>

void add_and_print(void *a, void *b, char type) 
{
if (type == 'i')
{
    int* val_1 = (int*)a;
    int* val_2 = (int*)b;
    int sum = *val_1 + *val_2;
    printf("%d",sum);
}
else if (type == 'f')
{
float* val_1_ptr = (float*)(a);
float* val_2_ptr = (float*)(b);
float sum = *val_1_ptr + *val_2_ptr;
printf("%.1f",sum);
}

}

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;
}
