C + + smart pointers Memory management is a common source of errors and bugs in C + +. In most cases, these bugs come from the use of dynamically allocated memory and pointers: when dynamically allocated memory is released multiple times, memory

Concept: Virtual functions (virtual function) are implemented by a virtual function table (virtual table), referred to as v-table. The role of learning virtual functions: Understand the mechanism of C + + to implement polymorphism, solve the problem

So far, I know that there are two kinds of heap, one is memory, a common use is dynamic memory allocation (this is the case in C + +), the other is here to discuss a data structure. A, heap In the data structure of the heap is called binary heap, as

typedef struct should be a C language design is not very reasonable place, the following explanation is still relatively clear. Notice different in C and C + +In C, you define a struct type with a typedef:typedef struct STUDENT{int A;}stu; Stu stu1;
