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=0,j;
    uint8_t temp=0,i;
    for(i=0,j=0 ; i<8 ,j<16 ;i++ ,j+=2) 
    {
        temp = val &((0x01)<<i);
        if(temp!=0)
        {
            res |= ((0x0001)<<j);
        }
    }
    return res;
}

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

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