126. Add Signed and Unsigned Integers Safely

#include <stdio.h>
#include <stdint.h>

int16_t signed_unsigned_sum(int8_t a, uint8_t b) {
    int16_t sum = (int16_t)a + (int16_t)b;
    // Your logic here
    return sum;
}

int main() {
    int8_t a;
    uint8_t b;
    scanf("%hhd %hhu", &a, &b);
    printf("%d", signed_unsigned_sum(a, b));
    return 0;
}
