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 uhRes = 0;

    for(int i = 7; i >= 0; --i)\
    {

        uhRes <<= 2;
        uint8_t ucBit = ((val >> i) & 0x01U);

        uhRes |= ucBit;
    }

    return uhRes;
}

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

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