The use of delegates is very simple, to understand the basic syntax can be open. But the real problem with delegating is that you don't know the scenario, like you've learned a new skill, but can't find any place to cast your fist. The puzzle has

Suppose you have the following classes:1 classBase {2 Public:3 Virtual voidDispintx =3) {//virtual function with default parameter value, 34cout "base::x is"Endl;5 }6 };7 classDerived: PublicBase {8 Public:9 Virtual voidDispintx = -) {/

1.& here is not the address calculation, but the role of the logo2. The effect of passing a reference to a function is the same as passing a pointer. At this point, the parameter of the function is used as the real parametric or an alias of the

The C language is often used in the following form when a function is passed.1 void Get (int **p)For this form, I wondered why I could not use *p as a formal parameter. Let's take a look at the code and the results1 void Get(int**p)2 {3printf"%p\n",*
