Preface Start TimeI learned C #2.0 and didn't fully learn it. After work, I am either busy with projects, or have a taste of various technologies, but I have no progress in language learning. It wasn't until six months ago that I started getting started with Python (purely a hobby, and I learned it intermittently) that I could do the same for programming! OriginalCodeYou can also write it like this! Indulge in various design patterns, frameworks, a

This is not what I wrote, I just see feel good, just paste the oh. ： Do not think that this topic is sensational, but in the current situation, C + + is required to exit the stage or to say that it is necessary to upgrade. I think that in the next year or two, as one of the criteria for programmer rating, C + + (whether MFC or BCB) will give way to three programming languages, 1.sun Java2.windows platform

Many beginners are accustomed to using char variables to receive the return values of functions such as getchar, GETC, and fgetc. In fact, this is not correct, and it implies a fatal error. The return values of functions such as getchar are int type. When these functions fail to be read or the file is read, EOF is returned. EOF is a macro. The standard specifies that its value must be a negative constant of the int type. Generally, the compiler defines EOF as-1. This is where the problem occurs.

c++| Program | Programmer eight. Class For object-oriented languages, classes are plays, and the use of classes in C # is similar to C + + and is somewhat different in detail. Let's first look at an example of a C # class: Cases: Class Myclass:mybasicclass//Note the base class does not require a write qualifier { priva

From http://blog.csdn.net/zhuweisky/article/details/415756 In C #, there are no free functions and no free variables. Everything must be encapsulated in the class. In C ++, using global variables for inter-function communication and inter-class communication are common methods. However, this becomes impossible in C, this indeed makes

Although most programmers are relieved to be able to continue using C + +, almost everyone suffers from the arcane syntax provided by managed C + +. Microsoft clearly sensed from feedbac

Write a function to exchange the values of two variables.C:Implementation of the error:void swap (intint j) { int t = i; = J; = t;}Because the function parameter of C is passed as a value (pass by value), the parameter is copied when it is passed, so the value is exchanged in the function.The right implementation:Pointer version:void swap (intint *j) { int t = *i; *i = *j; *j = t;}When a function is used to pass the address of a varia
