within the function defining the variable. After exiting the function, you cannot use it even though it still exists.(2) allow the static class of a construction class to assign initial values, such as an array, if the initial value is not given, the system automatically assigns 0 values.
静态变量static variable指的是该变量在内存中原地不动,而非说它的值不变。 块作用域的静态变量在程序离开他们所在的函数后,这些变量并不会消失,计算机在多次调用之间也会记录它们的值。 另外,对于块作用域的变量而言,非静态变量每次它的函数被调用时都会初始化该变量,但是静态变量在编译它的函数时只初始化一次,==...

global variable could be calleda, while a static member of the class would be calledSomeClass::a. Besides scoped naming, there are no other differences. (I deliberately ignore other C++-specific features, like access control, since they don't exist in C and this question is really about C...
C/C++中static、const和inline三种关键字的介绍 一、关于static static 是C++中很常用的修饰符,它被用来控制变量的存储方式和可见性,下面我将从 static 修饰符的产生原因、作用谈起,全面分析static 修饰符的实质。 static 的两大作用: 一、控制存储方式
conversion to void * in C and C++ Conversions from DWORD to Char[] Convert _TCHAR* variable to CString Convert a DLL to static Lib convert BYTE to _TCHAR Convert char * to LPCTSTR Convert char* to System::String^ convert const char * to LPTSTR convert cstring to char* Convert CString ...
static int my_static_variable = 0; // 静态变量的定义 } ``` 3. **静态块(局部变量):** - 在代码块内部的局部变量前加上 `static` 关键字,可以将局部变量定义为静态块。 - 静态块的生命周期与程序的生命周期相同,但是其作用域仅限于声明它的代码块内部。
