Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    uint8_t result = 0, index1=0;
    for(uint8_t index = 0;index<16;index+=2)
    {
        result |= (((val >> index) & 1) << index1);
        index1++;
    }
    return result;
}

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

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