Bit Reversal in an 8-bit Value

Code

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

uint8_t reverse_bits(uint8_t n) {
    uint8_t rev=0;
    for(int i=0;i<8;i++){
        rev <<= 1;
        rev |= n&1;
        n >>=1;
    }
    return rev;
}

int main() {
    uint8_t val;
    scanf("%hhu", &val);

    uint8_t result = reverse_bits(val);
    printf("%u", result);
    return 0;
}
