Modify Bytes in a 32-bit Value Using Union

Code

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

typedef union {
    uint32_t value;
    uint8_t bytes[4];
} Register;

// Write logic here using union to modify byte[1] and byte[2]
void modify_and_print(uint32_t input, uint8_t b1, uint8_t b2) {
    //Initialize a variable reg of type Register
    Register reg;

    //Assign the input value to the 'value' member in the union
    reg.value = input;

    //Modify the 2nd and 3rd bytes with new values using the concept of memory sharing in union and using bytes
    reg.bytes[1] = b1;
    reg.bytes[2] = b2;

    //print the modified 32-bit value
    printf("%u",reg.value);
}

int main() {
    uint32_t num;
    uint8_t b1, b2;
    scanf("%u %hhu %hhu", &num, &b1, &b2);
    modify_and_print(num, b1, b2);
    return 0;
}
