Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
   uint16_t res;
   int i=0,bit;
   while (i < 8)
   {
        bit = (val >> i) & 1;
        res |= (bit << (2 * i));
        i++;
   }
   return res;
}

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

    uint16_t result = spread_bits(val);
    printf("%u", result);
    return 0;
}
