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) {
    // Your code here
    Register r = {0};
    r.value = input;

    for (int8_t i = 0; i < 4; i++) {
        printf("%u", r.bytes[(uint8_t)i]);
        if (i != 3) {
            printf(" ");
        }
    }
}

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