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 res = 0;
    uint8_t temp_bit =0;
    for(int i =0 ;i < 8;i++)
    {
        if(val & (1 << i))
        {
            temp_bit = 1;
        }
        else
        {
            temp_bit = 0;
        }
        res |= (temp_bit << (i * 2));
        
    }
    return res;
}

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

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