Union Extract Bytes from a 32-bit Value

Code

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

//name is Register
typedef union {
    uint32_t reg; 
    uint8_t byte_arr[4];
} Register;

// Write logic here to extract bytes using union
void print_bytes(uint32_t input) {
    Register r; 
    r.reg = input;
    for (int i = 0; i < 4; i++)
    {
        printf("%u", r.byte_arr[i]);
        if (i < 3) printf(" ");
    }
}

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