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
The self-increment operator + + has both prefixes and suffixes, and in conjunction with the indirect access operator *, because of the effects of order, parentheses, and binding relationships, it is easy to misunderstand and produce the wrong
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. 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
+ + 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
C + + Specifies that the suffix form has an int type parameter, and when the function is called, the compiler passes a value of 0 as the int parameter to the function.The prefix form of the increment means "add and then retrieve", and the suffix
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.
Like C, Java provides a rich shortcut for computing. These shortcuts can make the code more refreshing, easier to input, and easier for readers to read.Two good shortcuts are the increment and decrement operators (often referred to as "AutoIncrement"
