"Process-oriented and object-oriented"* 1, process oriented: Focus on the process of solving a problem. The most important characteristic of the process is that a series of functions are solved to deal with the problem.* 2, Object oriented: Focus on

Extended question one: whether the parameters in the copy constructor are const to the effect of the copy constructor.Most people on the web can only interpret the problem as "when you don't want to make changes to the parameters, you need to add

The legacy coercion type conversion method is provided in the C language. Like what:int a = 1;Char *p = (char *) &a;The above will cast the address unit of a to a pointer of type char. For the moment, this is not to say whether the conversion
