This article mainly introduces "what are the programming skills of C++". In daily operation, I believe many people have doubts about the programming skills of C++. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what are the programming skills of C++?" Next, please follow the editor to study!

The basic types supported by C++ programming, such as int, double, bool, etc., can be said to follow the types in ISO-C++ in some ways-the same usage will get the same result in C++/CLI, such as addition or assignment. But C++/CLI also introduces something new to these basic types.

In the common type system (CTS), each basic type has a corresponding class in the System namespace (see Table 1). For example, int is actually completely equivalent to System::Int32. We can use either of them to declare an integer:

Int ival = 0; Int32 ival2 = 0

For portability, we recommend that you use built-in keywords instead of class names in the System namespace when using these basic types.

The public static members of a class in the System namespace can be accessed either through built-in keywords or through the class name in the System namespace. For example, to get a range of values for a numeric type, we can directly use the built-in keywords to access its static properties C++ programming and MinValue.

Note that parentheses outside 5 are necessary because it causes the compiler to bind the following member selection operator dot to the integer 5 instead of '5.' Parse to a literal constant of type double-- in that case, the following ToString () will become illegal. Why do we need to do this sometimes? One possibility is that it is more efficient to pass a string to a member function of Console than to pass the actual numeric value.

At this point, the study of "what are the programming skills of C++" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
