68. Union Extract Bytes from a 32-bit Value

#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) {
    //1. create a union instance
    Register reg;
    //2. Assign the 32 bit input to the 32 bit value of the union
    reg.value = input;
    //3. We can now read the input as bytes by accessing the byte format from the union
    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;
}
