Exceptions are anomalous behaviors that exist at run time that are outside the scope of the function's normal function. Typical exceptions include losing database connections, encountering unexpected inputs, and so on. Handling anomalies can be the

C + + 's main function can have no input parameters, or can have input parameters, and can only have two parameters, it is customary to coding as follows:int Main (intcharint main (intChar* * argv)where argc = argument count: Indicates the number of

1, a program compiled from the source file to build the executable file steps:Precompiled--compile-and-link(1) Pre-compilation, that is preprocessing, mainly processing in the source code files with "#" to start the pre-compilation instructions,

In this paper, a simple example to illustrate the implementation of the C # Strategy model, shared for everyone to reference. The implementation method is as follows:In general, when there are multiple implementations of an action, you might

Definition: When defining generics , we can use where to limit the range of parameters .Use: When using generics , you must respect the scope of the where restriction parameter , or the compilation will not pass.Six Types of Constraints:T: Class
