Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t reg){
      uint8_t x = 0;
      for(uint8_t i = 0; i < 16; i += 2){
        x =  x | ( ((reg >> i)&0x0001) <<(i/2) ) ;
      }     
      return x; 
}

int main(){
    uint16_t value; 
    scanf("%hu",&value); 
    printf("%hhu",compress_bits(value));
    return 0;
}
