pre increment and post increment operator in c

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

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

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

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

Next, let's take a look at the example of the c ++ overload post-auto-addition operator. If you need to learn the C ++ auto-addition operator, you can refer to it. The Code is as follows: Copy code # Include Using namespace

The code is as follows:Copy code # Include Using namespace std;Class num{Public:Int x;Num () {n = 1; cout Num (int I) {n = I; cout Num (const num & s) {this-> n = s. n; cout ~ Num () {cout Int get () const {return n ;}Void set (int x) {n = x

the Java operators include the following: arithmetic operators, comparison operators, bitwise operators, logical operators, assignment operators, and other operators. (The figure is from the network)simple operators, it is not too much to introduce

+ + increments each have pre-increment and post-increment differences, while overloaded operators, although the function names are the same, there should be a corresponding difference. The result of the increment operator before an integer variable
