The pointer function that needs to be used. By using the pointer function as the address to receive the function address, to achieve the purpose of delegating other functions to implement a method.The following sticker codevoidfunction1

by Result_ofmultimap::type, person>std::result_of ::type can get the return value of a function, no magic number, no declval tedious notation, very elegant. In fact, look at the source code know result_of inside is through the declval realization,

The implementation of a delegate is that the compiler defines a class by itself: There are three important parameters 1. Set up an Action object, 2. Specify delegate method 3. Delegation chainLook at the next example: 1234567891011121314

Three examples of "synchronous invocation", "Asynchronous Call", "asynchronous callback" are #委托的异步调用本文将主要通过 to explain the differences and pros and cons of executing the same "addition class" with a delegate.

In method parameter passing, you can use both the ref and out keywords, but be aware that the ref and out parameters are passed differently. Using System; Class program { static void Main () {     program obj = new program ();     int score = 55;

Is there a memory leakage in Java ?, Memory leakage in java Theoretically, Java does not cause memory leakage because of the garbage collection mechanism (GC ). (This is also an important reason why Java is widely used in server-side programming .)
