C++

Review C + +, it is necessary to some things to make notes, easy to learn later, if there is a problem, welcome to put forward.First, the two most common composite types should be references and pointers.A composite type is a type that is defined on

int arr[]; errorint arr[23]; ARR={23,23} error (only initialized at the same time when an array is defined)int count = 3; int Arr[count] ={23,23,23} error (must be constant) if you want to define an array of simultaneous initialization, the number

The 1 C + + language does not explicitly specify the order in which arguments are evaluated when the function is called, but rather allows the compiler to determine the job order of the arguments themselves, based on the need to optimize the code.

1. Two-dimensional array:Example: int a[5][6]: 5 rows 6 ColumnsWhen stored in physical memory, it is stored as an array.Note: Initialization of rows can be saved, columns cannot be empty, array names are not assignable2. Continue: The end of this

1. Overloading of assignment operators:Under what circumstances do I need an overload of the assignment operator? When there are pointer variables pointing to space in a class, you need to overload the assignment operator for deep copies. Shallow
