Bit Reversal in an 8-bit Value

Code

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

uint8_t reverse_bits(uint8_t val) {
    uint8_t final = 0;
    for (int i = 0; i < 8; i++) {
        if (val & (1 << i)) {
            final |= (1 << (7 - i));
        }
    }
    return final;
}

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

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