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 result = 0;
    int index = 0 ; 
    for (int i =0 ; i < 8 ; i++)
    {
            if (val & (1 << i))
            {
                //printf("bit is set %d \n", i);
                result |= (1 << index);
            }
            index += 2;

    }
    return result;
}

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

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