Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {

    uint16_t spread_bits = 0x0;

    uint8_t counter_16_t = 0;

    for(uint8_t i=0; i<8; i++)
    {
        if((val>>i)&1)
        {
            spread_bits |= (1<<counter_16_t);
        }

        counter_16_t+=2;
    }

    return spread_bits;
}

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

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