When you rewrite operator new by yourself (cla10 explains why you sometimes rewrite it), it is important that the behavior provided by the function should be consistent with the default operator new of the system. In practice, the correct return value must be obtained. When the available memory is insufficient, the error processing function must be called (see Article 7). The 0-byte memory request must be p

The combination of the C ++ operator and the operator Operator overloading is one of the important features of C ++. This article introduces the usage of Operator overloading in the C ++ standard library. If you can easily master the operators of C ++, you do not need to continue reading them. The benefit of

C + + single-eye operator overloadingThe monocular operator has only one operand, such as!a,-b,c,*p, and the most commonly used ++i and-I. The method of overloading the monocular operator is similar to that of overloaded binocular operators. However, because the monocular operator has only one operand, the

Operator new and new operator in C ++ look pretty different from each other. Operator new (1) only allocates the required space and does not call constructors of related objects. When the requested space cannot be allocated,-> If new_handler exists, new_handler is called; otherwise-> if no exception is required ), an exception occurs when bad_alloc is executed. O

This article describes the differences and linkages between the three types of new/delete.New operatorThe new operator (new operator) is an operator commonly used in our C + +, such as a * a = new A; Create a pointer to a object.The new operator is divided into two steps:1. Type-based size calls

1:C ++ standard: an allocation function shall be a class member function or a global function; A program is ill-formed if an allocation function is declared in a namespace scope other than global scope or declared static in global scope. It must be a global function or a class member function, but not a namespace or static global function outside the global. 2: New operator actionFor the following code:Foo * P = new (parameter 1, parameter 2 ,...... )
