I believe many cppers, like me, have been hovering in pointers and references for a long time. We often mix pointers and references, especially when we see the usage listed in the question, which really hurt our brains. Later, I used it in the

Preface As for pointers, we first need to figure out four points: the pointer type, the pointer to the type, the value of the pointer, and the value the pointer points to. If this is not very clear, please refer to here URL:

1 start with const int IYou know, when declaring a variable, int I is like this; this I may be re-assigned to it. As follows:Int I = 0;//...I = 20; // The value is assigned again here.However, one day my program may need such a variable (temporarily

Similarity point All use typedef to assign a simple name to a complex combination of types consisting of the underlying data type; All follow the tradition of C--the type defined by typedef ends with "_t"; Both can play a role in

Today with a few classmates see a function pointer definition:void (*f (int, void (*) (int))) (int)Previously seen in the C trap pit fails inside, but the article is described in detail, but often so that beginners do not grasp the focus, the result
