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 num = 0x0;

    for(int i=0; i<16; i++){
        if(i % 2 == 0){
            if(val & (1 << (i/2))){
                num = num | (1 << i);
            }
            else{
                num = num | (0 << i);
            }
        }
        // else{
        //     num = num | (0 << i);
        // }
        

    }
    return num;
}

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

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