void pointer and Casting

Code

#include <stdio.h>

void add_and_print(void *a, void *b, char type) 
{
   int sum;
    if (type == 'i') 
    {
        int sum =(*(int *)a)  +(*(int *)b) ;
        printf("%d\n",sum);
    } 
    else if (type == 'f') 
    {
        float sum =(*(float *)a)  +(*(float *)b) ;
        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;
