Union Extract Bytes from a 32-bit Value

Code

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

typedef union {
    uint32_t value;
    uint8_t bytes[4];
} Register;

// Write logic here to extract bytes using union
void print_bytes(uint32_t input) {
    uint8_t *bytes = ((Register*)&input)->bytes;
    printf("%d %d %d %d", bytes[0], bytes[1], bytes[2], bytes[3]);
}

int main() {
    uint32_t num;
    scanf("%u", &num);
    print_bytes(num);
    return 0;
}
