void pointer and Casting

Check and type cast accordingly

#include <stdio.h>
/*
union types {
    float fr;
    int ir;
};
*/
void add_and_print(void *a, void *b, char type) {
    // Write your logic here using type casting
//    types result;
    if(type == 'f') {
//        result.fr = *(float*)a + *(float*)b;
        float result = *(float*)a + *(float*)b;
        printf("%.1f", result);
    }
    else {
        int result = *(int*)a + *(int*)b ; 
//        result.ir = *(int*)a + *(int*)b ;
        printf("%d", result);
    }

}

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;
}
