Rotate Right in a 32-bit Register

Code

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

uint32_t rotate_right(uint32_t reg, uint8_t n) 
{
    uint32_t mask=reg&((1<<n)-1); //we need to extract the data corresponding to the bits on LSB.
    return (reg>>n)|(mask<<(32-n)); //perform right shift and OR with shifted mask.
}

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