Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    uint16_t result;
    uint8_t pos;
    pos = 0;

    for (int i=0; i<16; i++) {
        if (i%2 != 0) {                 // clear every odd bit position
            result &= ~(1 << i);
        } else {
            if (val & (1 << pos)) {     // match what the original register bit value is
                result |= (1 << i);
            } else {
                result &= ~(1 << i);
            }
            pos = pos + 1;
        }
    }
    return result;
}

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

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