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;


void print_bytes(uint32_t input) {
   Register reg;
   reg.value = input;
   for(int i=0;i<4;i++){
    printf("%d ",reg.bytes[i] );
   }
  
}

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