Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
   
   uint16_t b=0x0;

   for(int i=0;i<8;i++)
   {
    int a=(val>>i)&1;
    b|=a<<(i*2);
   

   }

    return b;
}

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

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