solid design principles c#

In general, the so-called WIN32 application development, is in the C language level, directly using the WIN32 API (application Programming Interface: System open, to the programmer to use the interface. To develop Windows applications or System programs. Although there are not many people who develop applications directly with the Win32 API, a deep understanding of the principles of Windows system

This is the topic that a netizen asked questions when I first got to work this morning. I personally felt that it was quite common. So I copied my QQ message and compiled it into an article. This is not a big topic, but I think the design principles embodied by professional programmers in Coding are of great reference. You can refer to them.

The default is to use vectors. --alex StepanovThe most useful vector in the C + + standard library is vectors. A vector provides a series of elements of a specified type. You can find an element by its index (subscript), use push_back () to extend the vector, use size () to get the number of elements in a vector, and prevent access to the out-of-bounds vector elements. The standard library vector is a convenient, flexible, efficient (time and space),

What is the basic object-oriented principle?Design principles are basic tools. applying these rules can enable yourCodeIt is more flexible, easier to maintain, and easier to expand.

. Also, there is no subclass of struct types, so there is no polymorphism in some way, and there is no cutting (slicing) effect that may occur when C + + objects are passed. However, the cost of a value copy is still not small. Especially in the case of a large value type, the problem is more serious. In fact, in the design guidelines for Class Library developers documentation for the. NET Framework, there

have child classes. Therefore, to some extent, there is no polymorphism, and there is no slicing effect that may occur when the C ++ object transmits values. However, the cost of copying values is not small. Especially when the value type is large, the problem is serious. In fact. in the design guidelines for class library developers document of the.

applications, using pointer arithmetic is more convenient.The name of the array represents all the elements of the array. Example: Char ch[100]; The size of CH sizeof (CH) is 100. However, the name of the array can be transformed (degraded) into pointers. For example: char * p = ch;PalindromeUse a string to implement a palindrome. Track the progress of character comparisons using the string type of the standard library and an index of type int:BOOL Is_palindrome (const string s) {int first = 0;
