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
// }

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

typedef union{

    uint32_t value;
    uint8_t array[4];
}Register;


void printf_bytes(uint32_t input){

    Register reg;
    reg.value = input;


    for(int i=0;i<4;i++){

        printf("%hhu ",reg.array[i]);
    }
}

int main(){

    uint32_t input;

    scanf("%u",&input);

    printf_bytes(input);

    return 0;
}
