void pointer and Casting

Code

#include <stdio.h>

void add_and_print(void *a, void *b, char type) {
    // Write your logic here using type casting

    if(type == 'i'){
        int a_int = *(int*)a;
        int b_int = *(int*)b;
        printf("%d",a_int + b_int);
    }else{
        float a_flt = *(float*)a;
        float b_flt = *(float*)b;
        printf("%0.1f",a_flt + b_flt);
    }
}

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;
}
