Bit Reversal in an 8-bit Value

Code

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

uint8_t reverse_bits(uint8_t val) {
    uint8_t reverseReg = 0;
    for(uint8_t i=0;i<8;i++){
       if((val>>(8-1-i)) & 0x01) reverseReg |= 1<<i;
    }
    return reverseReg;
}

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

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