Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint16_t result = 0;
    
    for(int8_t i = 0; i <= 8 ; i++)
    {
        if (val & (1 << i))
        {
            
            result |= (1 << (i * 2));
        }
        else
        {
           
        }
    }
    
    return result;
    val = result;
}

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

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