Bit Reversal in an 8-bit Value

Code

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

uint8_t reverse_bits(uint8_t val) 
{
    int i= 0x00;
    uint8_t num = 0x00;
    uint8_t result = 0x00;
    for(int i = 7; i >= 0; i--)
    {
        num = (val >> i) & 1;
        result |= num << (7 - i);
    }
    return result;
}

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

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