operator= 用于不匹配的类型

Question

I have the code below where I am trying to create an operator= for my class and a char. The class has a constructor for the char.

It when I call the = operator it will go into the class and assign the class b correctly, but when it returns the byte1 isn't updated. I'm not sure why that would be.

Part of my class:

Byte operator=(unsigned char lhs)
{
    Byte b(lhs);
    return b;
}

int main()
{
    unsigned char c1{ 'a' };
    Binary::Byte byte1;
    byte1 = c1;
}

Answer 1

As @HTNW said I was failing to return *this. Should be:

Byte operator=(unsigned char lhs)

    {
        Byte b(lhs);
        *this = b;
        return *this;
    }
