C++

First, the default parameters of the function:The so-called default parameter is actually a function that can omit arguments when called, such as:void Fun (int a=0,int b=0) { cout" "Endl;} int Main () {fun (); // 0 0 return 0 ;}Problems

inline functions in C + +:Inline functions are preceded by the Declaration and definition of a function with the "inline" keyword, and inline functions, like regular functions, pass arguments by value, and if the argument is an expression, such as 4.

1. Definition:The function body code of the called function is inserted directly into the function to be invoked, rather than through a call statement.2, the way:(1), the definition of the class in vitro:When outside the definition body of a class,

Data member Alignment rules: A data member of a struct (struct or union Union), where the first data member is placed at offset 0, where the starting position of each data member store is to begin with an integer multiple of that member size (for

/*when using the pointer p to store space in the heap, before assigning the second block of memory to P, we want to release the memory space that P originally pointed to, so that no memory leaks are possible, otherwise the memory space of P's

Ready to take the time to learn C + +, do not know if they can persist, to Baidu to check the introduction, most friends are selected with VC + + or VS, and I use the C-free 5, installation package is only more than 10 trillion.It is also convenient

The memory distribution that C + + programs occupy:Stack: The compiler automatically allocates releases, stores the function's parameter values, the values of local variables, and so on. It operates in a manner similar to a stack in a data structure.

In C language, you can create a temporary variable to achieve the exchange of two variables, when you do not allow the creation of temporary variables, how to implement the two variables Exchange?Suppose there are two variables num1 and num2, and

Constructors and destructorsfunction of the constructor: 1. Initializing objects 2. Assigning resources to Objects 3. Other work that the programmer believes should be done at this timeInitialize the object, why to automatically call the constructor

We define a pointer to be sure to use him to save a memory address, join us not to do so,Then the pointer is a runaway pointer he can point to any address, and the value of that address is modified or deleted, the consequences are very scaryThe

1. Process fragmentationBSS segment (BSS segment): Holds a global object that is uninitialized (or zero-initialization, as described in C + + object initialization), and belongs to static memory allocation. (BSS is all called "Block Started by
