post increment operator

Prefix and suffix of the auto-increment and auto-increment operators, and suffix of the operator prefix. There is such a question in the exam: 12 inta = 4;(++a) += i; Evaluate the value of a. The correct answer is 10. If you think

Absrtact: In C language teaching, the self-increment self-subtraction operator is widely used, and it has certain skill and difficulty. Among the many operators, the self-increment decrement operator is the most difficult to understand and the most

1. Since the pre-increment and post-increment operators are unary operators, the overloads are distinguished by adding an int parameter (dummy parameter) to the post-increment, and when the post-increment is called, the compiler automatically

Prefix increment and decrement operators: + + and-Grammar + + Unary-expression––unary-expression NoteThe prefix increment operator (+ +) adds 1 to its operand, which is the result of an expression. The operand must be a left value that is not a

In the previous chapters we have been exposed to the overload of the increment operator, at that time we did not distinguish between the previous increment and the ++a difference, under normal circumstances we are not separate from the a++, but it

1. Increment decrement operatorThe C + + language does not require that the increment decrement operator be a member of a class. But because they change exactly the state of the object being manipulated. Therefore, it is recommended to set the

Found a good article:Reproduced:This paper mainly summarizes the operator overloading and C + + operator overloading summary from C + +.What is operator overloadingOperator overloading is to give multiple meanings to existing operators, causing

Transferred from: http://bbs.csdn.net/topics/330189207C language's self-increment + +, self-subtraction-operator has always been a problem for beginners, and even a lot of veteran will be confused, recently I saw a problem on the Internet:#include

The operands of predefined operators in C + + can only be basic data types, and in fact, for many user-defined types, similar operations are Required. For example:Class Complex{PublicComplex (double r=0.0,double i=0.0) {real=r;imag=i;}void Display ()
