What is the difference between:

int main()
{
    uint8_t data = 32;
    uint16_t calc;
    
    calc = (~data) + 12;
    
    std::cout<< calc;
}

Output: 65515

and

int main()
{
    uint8_t data = 32;
    uint16_t calc;
    
    data = ~data;
    calc = data + 12;
    std::cout<< calc;
}

Output: 235

I understand that “~” performs the 1’s complement of data but why is the result of calc different?
