Bit Spreading Interleave Bits with Zeros

Code

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

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

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

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