Thus, we define truncString function that takes the string and several characters to truncate from the string. The number can be negative, indicating the side from which to remove the given number of chars. Next, we retrieve the string length using the strlen function, which implies that the...
This sample creates an unbound delegate to a property's accessor functions:C++ คัดลอก // unbound_delegates_3.cpp // compile with: /clr ref struct B { property int P1 { int get() { return m_i; } void set(int i) { m_i = i; } } private: int m_i; }; ...

On a Linux machine, you don’t have to be a programmer to take advantage of development tools, but when working with the system, you should know something about programming tools because they play a larger role in managing Unix systems than in other operating systems. At the very least, yo...

Operators are a way to create expressions in C++. You can overload them, which means you can define new meanings for the operators.The input and output stream insertion operators read or write information from a file. In C++, the stream insertion operator << is used for output, while >>...

We define both of our functions. Now, we call them in the “main” function to see the output. The main() section of the program begins. When a class is defined, it does not have any storage. The only defined part of the object is its specification. We need to first generate a cl...
例如我们常用的define include if endif等等。这离我们来看下我们最常用的预处理语句:#include是如何工作的。#include语句处理方式十分简单,我们只需要制定他需要 include的文件,然后预处理器(pre-processer)会打开对应文件,读取所有的内容并把它包含到这个文件中,下面用代码举例:...
