Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val)
{
   uint16_t final_value = 0x0000;
   final_value = val&0x0001;
   for(int i=1;i<8;i++)
   {
       final_value += ((val<<i)&(0x0001<<(2*i)));
   }
   return final_value;
}

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

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