void pointer and Casting

Code

#include <stdio.h>

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