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 x=0;
    int j;
    for(int i=0;i<=15;i++){
        if(i%2==0){
            j=i/2;
            if(val &(1<<j)){
                x |=(1<<i);
            }
        }
        else{
            x &=~(1<<i);
        }

    }
    return x;
}

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

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