C++

The C language is cross-platform, but the program that it compiles on Windows is not able to execute directly on the Linux platform and requires the source code to be recompiled on the Linux platform. GCC generally needs to complete preprocessing

The strong internal strength martial arts master moves are often bland. Similarly, the programmer does not use strange trick to write programs. A good programming style is a prerequisite for producing high-quality programs. below toC + +For example,

Once you know how TCHAR and _t work, the problem is simple. The basic idea is that TCHAR is either char or wchar_t, depending on the value of _unicode:#ifdef _unicode typedef wchar_t TCHAR; #define __t (x) L # # x#else char TCHAR ;

STLPractice and Analysis--the structure of a generic algorithmIntroduction:just as all the containers are built in a consistent design pattern , The algorithm also has a common design basis . The most important property of the algorithm is the type

int a[] = {0};The compiler assigns the first initialization value (here, 0) to the first element of the array, and then assigns the remaining elements with the default value of 0. If the initial value is not given, the compiler does not do the

Many times, we develop a program that requires a single run of functionality, that is, the entire application only allows running at most one instance at a time, repeatedly running, activating the current strength, showing its interface.In a C #

Recommendation 34: Setting constraints for generic parametersThe word "constraint" may cause ambiguity, and some would argue that restricting the use of generic parameter constraints is the opposite of the actual situation. A generic parameter

Recommendation 32: Always prioritize genericsThe advantages of generics are manifold, whether generic or generic methods have both reusability, type safety, and high efficiency, which are not available for non-generic and non-generic methods.In the
