Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    uint16_t output = 0;
    int bitPos = 0;
    for (int i = 0; i < 16; i++) {
        if (i % 2 == 0) {
            output |= ((val & (1 << bitPos)) >> bitPos) << i;
            bitPos++;
        }
    }
    return output;
}

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

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