C++

In C + +, programmers use templates to write type-independent code, improve source code reuse, and use the appropriate, greatly improving the development efficiency. Previously, you could use a macro to implement the functionality of the template,

Mallocint* p = (int *) malloc (sizeof (int) *128);Allocate 128 integer storage units (which can be replaced according to actual needs) and store the first address of these 128 contiguous integer storage units in the pointer variable p.This can

Polymorphism is the phenomenon that the same symbol or name has different interpretations in different situations. Polymorphism has two forms of expression: Compile-time polymorphism: The same object receives the same message but produces a
