Rotate Right in a 32-bit Register

Code

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

#define SHIFT_RIGHT(reg,n) (reg>>(n))
#define WRAP_LEFT(reg,n) (reg<<(32-n))
#define MASK_32_BIT ((1U<<32)-1)

uint32_t rotate_right(uint32_t reg, uint8_t n) {
    // Your code here
    return reg =( SHIFT_RIGHT(reg,n) | WRAP_LEFT(reg,n) )& MASK_32_BIT;
}

int main() {
    uint32_t reg;
    uint8_t n;
    scanf("%u %hhu", &reg, &n);
    printf("%u", rotate_right(reg, n));
    return 0;
}
