First, make clear how much space each data type occupies. For example, whether int is a 2-byte or 4-byte space:In TC, int is 2 bytes (mainly because the TC is 16 bits, so the int type is also 16 bits)VC + +, int is 4 bytes, because most of the

I believe that this may be a lot of friends of the problem, I have such a feeling before, programming to a certain time, the ability to find the bottleneck, neither deep nor solid, dabbler. For example: You use Java and. NET for a long time, these

I. OverviewThe C language cannot directly define a dynamic array, and the array must determine the length at initialization time.If you want to determine the length of the array while the program is running, you need to go to the system to request a

16.1 How to convert a base data type to a CString typeUsing the Format method of CStringvoid CDemoView::OnDraw(CDC* pDC){ int a = 100; double b = 1.23; //将整型转换成CString CString str1 = _T(""); str1.Format(_T("%d"), a);

Indefinite parameters that year as a C + + language A special feature is respected by many people, but in fact, this technology does not apply a lot. In addition to formatting the output, I really didn't see much of the app. The main reason is that

Optional arguments for functionsThe C language allows you to define functions that have a variable number of arguments, called variadic functions. The Variadic function requires a fixed number of mandatory arguments, followed by a variable number of

The memory used by a program compiled by C + + is divided into the following sections 1, stack (stack)-Automatically allocated by the compiler to release, store the function's parameter value, the value of the local variable, and so on.  It operates

Emit is intended to dynamically build a dynamic library that can be executed (and, of course, reflected) or can only be reflected.Personally, the use of emit in situations where reflection has to be used can make for a lot of room for efficiency
