Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    int res=0; //uint16_t

    for(int i=0; i<8;i++)
    {
        int bit=(val>>i)&1; //uint8_t
        res |= (bit<<2*i);
    }
    return res;
     
}

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

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