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
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
overloaded operators and conversions--Self-increment/self-decrement operatorIntroduction:Self-increment, the decrement operator is often implemented by classes such as iterators that provide pointers-like behavior to access elements in a sequence.
Increment decrement operator
Before increment ++++ $a $ A increments by 1 and then returns $ A
After increment + + + $a first return $ A, then $ A since 1
Before decrement----$a $ A self minus 1 and then return $ A
After decrement--$a--returns $ A,

Look at the operator overloads of C #, and find that they are not the same as C + +. Just been in the C # self-increment operator pit, now to share.First define a class class A { publicint i; Public A (int i) {
The following is a detailed summary of the description and function of various operational symbols in C #first, []square brackets ([]) are used for arrays, indexers, and properties, and also for pointers.1, the array type is a type followed by
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
