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

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

Clause 5: Be careful with user-defined conversion functions   C ++ allows the compiler to implicitly convert two data types. (Implicit conversion). First, C ++ inherits the type conversion policy of C language. In addition, C ++ has two types of

Therefore, we should use int for storage, and perform some processing on the id during display, so that it is easy to tell which table the id belongs. A database table usually has an auto-incrementing primary key named id, whose field type is

Believe that a lot of people have just started to learn programming, but also for this problem, the prefix and suffix, in a long time ago, there is no way to distinguish between + + and-operator prefix and suffix of the call. However, the C + + has

Requirement 1: Order number requirements unique, not too long, self-increment, but not through the morning order number and the night order number subtraction to calculate the platform about a day of the single volumeRequirement 2: Request to

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

The following code:public class Example025 {public static void main (string[] args) {int ape = 100;int it = 100;int ape_it = 100;for (int i = 0; I Output Result:Ape = 0it = 100ape_it = 0Cause Analysis: There should be no objection to the ape's

What is the difference between adding 1 by prefix and adding 1 by suffix? prefix 1 and The increment operator ++ is a unary operator. The increment operator can appear before the variable as the prefix or suffix after the variable. What is the
