In C language, information encapsulation is weaker, only the file scope of static variables.Assumptions are not constrained. Very easy causes global variables to fly.Assume that you define a global structure body. Put the global variables in this

Some conversions of enumerations are often encountered in the work, especially to get enumeration notes, etc. specially collated methods later usedpublic void TestMethod1 () {Testenumone colorenum = testenumone.red; int colorvalue = 0x0000

Hello, crossing. The last time we were talking about a sample of inter-thread communication, this time we say the example is: thread synchronization . Gossip Hugh, words return to the positive. Let's talk C chestnuts together!Crossing, mention

Brief introduction:The creation of a managed thread requires thousands of CPU cycles, and there is a noticeable overhead when a thread switch occurs. It is a way to improve the efficiency of the system to consider the reuse of threads and avoid

Relatively large projects sometimes compare cards, although there is a GC automatic cleaning mechanism, but there is still unsatisfactory place. So try to manually write a timer in the project startup file, clean the memory periodically, and speed

Considerations for the interface:1) interfaces are implementations, and abstract methods are inherited2) You can have common methods in the class that implements the interface3) Define the interface using the keyword Internet4) Implement Interface
