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;
    r.value= input;
    printf("%d ", r.bytes[0]);
    printf("%d ", r.bytes[1]);
    printf("%d ", r.bytes[2]);
    printf("%d", r.bytes[3]);
}

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

Solving Approach

declare a variable of type register

transfer the value of input to the register value

pickup the bytes from the register value
