Bit Reversal in an 8-bit Value

Code

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

uint8_t reverse_bits(uint8_t val) {
    
    uint8_t copy_val = 0;

    for(int i=7,j=0; i>=0; i--,j++)
    {
        if((val>>j)&1)
        {
            copy_val |= (1<<i);
        }

    }

    return copy_val;
}

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

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