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 = 0x0000;
    for (int i = 16 ; i>=0;i-=2) {
        reg = reg|(0<<i);
    }
    for (int i = 7 ; i>=0;i--) {
        if(val & (1<<i))
           reg = reg|(1<<(i*2));
    }
    return reg;
}

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

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