Bit Reversal in an 8-bit Value

Code

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

uint8_t reverse_bits(uint8_t val) {
    // Your logic here
    // printf("%08b\n", val);
    uint8_t tmp = 0;
    for(int i = 0; i < 8; i++) {
        tmp |= ((val >> i) & 1) << (7-i);   
    }
    // printf("%08b\n", tmp);
    return tmp;
}

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

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