Here are some of the key points that apply to all C + + program apes. I say they are the most important, because these points are mentioned in the C + + book or you usually can not find the site. For example, pointers to members, which are not

the best way to find a program error is to execute the program. During the execution of the program, we use our eyes or the tools of automated testing such as assertions and subsystem conformance checks we write to discover errors. While assertions

When a function is not part of a specific instance and belongs to the entire class, then this function is best written as a static member function, so that it can be called directly with the class nameClass::func ()For general member functions when

#include using namespacestd;intMainintARGC, _tchar*argv[]) { inta[5]; intb[4] = {1,2,3,4}; CharC[] ="1234"; int*d=New int[4]; *d =1; * (d+1) =2; * (d+2) =3; * (d+3) =4; printf ("a length =%d\n",sizeof(a)); printf ("b length =%d\n",sizeof(b));

I. OverviewIn today's era of multi-core development, programmers are required to write high-concurrency programs, while multiple cores are typically used in two ways: multithreaded or multi-process. If a thread or process is temporarily generated

The C + + built-in array supports the container's mechanism, but it does not support the semantics of container abstraction. To solve this problem we implement this class ourselves. in standard C + +, it is implemented with container vectors (vector)

In a C program, a file is represented by a file pointer or a file descriptor. ISO C's Standard i/0 library functions (fopen, Fclose, Fread, Fwrite, fscanf, fprintf, etc.) use file descriptors, Unix I/O functions (open, close, read, write, IOCTL).

1. Provide access to the original resource in the resource management class The first few articles are great, they are a bulwark against resource leaks, but many APIs point directly to resources, and at this point we need direct access to the

Static class An important difference between static and non-static classes is that static classes cannot be instantiated.That is to say, you cannot use the new keyword to create a variable of the static class type. When declaring a class, using the

Another concept originated from functional programming languages is added to the C # and VB camps, which are known as pattern matching. At first glance, pattern matching works like a switch/SELECT statement block, but it has many powerful functions.

Original article: C # parallel programming-related concepts For more information, see the C ++ concurrent programming high-level tutorial. Background Today's computers have at least one dual-core microprocessor, which is very common with quad-core
