Bit Reversal in an 8-bit Value

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

uint8_t reverse_bits(uint8_t val) {
    // Your logic here
uint8_t a=0;
int i=0;
while(i<8){
if((val&(1<<i))>0){
    a+=1<<(7-i);
}
i++;
}
    return a;
}

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

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