Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) 
{
    uint8_t ans=0x00; //initializing answer with zero in 8bit format.
    int i;
    for(i=0;i<16;i=i+2)
    {
        if(val&(1<<i)) //when ever the bit in even positions is set, we need to set the bit high in ans in pos:(i/2).
        {
            ans=ans|(1<<(i/2));
        }
    }
    return ans;
}

int main() 
{
    uint16_t val;
    scanf("%hu", &val);

    uint8_t result = compress_bits(val);
    printf("%u", result);
    return 0;
}
