Vector vectors:Vector vectors are an object entity that can accommodate many other types of elements and are therefore called containers. As with string, vectors belong to a custom data type in the STL (Standard Template Library), which can be

1.c++ References:A reference is an alias to a variable (the target), which is equivalent to the same person having two names, regardless of which name actually refers to the same person. Similarly, on a reference, the action on the reference is

The C + + programming language is a widely used computer programming language that supports a variety of programming. Today we will give you a detailed introduction of the C + + polymorphism of some basic knowledge, in order to facilitate everyone

The difficulty in implementing multiplication tables in C is how to control the format of the data output, which is a deep understanding of nested for loops. First, the outer loop is assigned one time, the inner loop executes once, and for the

Prime number, also known as prime number, has an infinite number. A natural number greater than 1, except 1 and itself, cannot be divided by other natural numbers (prime numbers), in other words the number is no longer a factor other than 1 and

What is a delegate A delegate is a class that defines a method's type so that it can be passed as a parameter to another method, which dynamically assigns the method to the parameter, avoids the large use of the If-else (Switch) statement

Reflection Definition: the ability to review metadata and collect type information about it. Metadata (the most basic data unit after compilation) is a whole bunch of tables, and when the assembly or module is compiled, the compiler creates a class
