C/C++: static variables static variable can only be initialized once. Compiler persist the variable till the end of the program. Eg: #include <iostream>int* a =NULL;voidmy_delete() {staticintdeleted =0; std::cout<<"deleted ="<< deleted ++ <<std::endl; std::cout<<"&deleted ="<<...
C语言之static静态变量 C语言之static静态变量 A static variable is a lifetime that is the amount of the entire source. Although it cannot be used when it leaves the function that defines it, it can be used again if the function that defines it is called again, and the value left after ...
这对于在C/C++或任何其他需要存储函数先前状态的应用程序中实现协程非常有用。 // C++ program to demonstrate // the use of static Static // variables in a Function #include <iostream> #include <string> using namespace std; void demo() { // static variable static int count = 0; cout << ...
For example, in the following program there are two instances: void fun(int ) and void fun(double ). So two copies of static variable i exist. 1#include <iostream>2usingnamespacestd;34template <typename T>voidfun(constT&x)5{6staticinti =10;7cout << ++i;8return;9}1011intmain()12{...

An auto variable created a new each time when the function (in which variable is declared) is called and destroyed when the program's execution leaves the function.Example#include <stdio.h> int main() { int a; auto int b; a=10; b=20; printf("a=%d, b=%d\n",a,b); return 0;...

In the functionmyFunction()definition,varis not static, it’s alocal/automatic variablehere and it will be declared every time of program’s execution will move the function definition; that’s why on every calling ofmyFunction(), value ofvarwill be 1....
