Bit Reversal in an 8-bit Value

Code

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

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

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

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