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 reg = 0;
    for (int i= 0 ; i < 8 ; i ++)
    {
        uint8_t bit  = (val >> i) & 1;
        //printf("%d\n" , bit);
        reg |= (bit << (2 * i));             // Place in 2*i position
    }

    return reg;
}

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

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