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 << ...
C# Equivalent to C/C++ static variable in a function? Jan 4 '06, 02:45 PM Back in the "old" C/C++ days, I used to declare static variables inside functions. Something like... // just a silly example to demonstrate the technique int foo(void) { static int NextVal = 0; NextVal ...

In this example we are declare a static variable var inside the function myFunction() and returning the value of var. Function myFunction() is caling inside the main() function.Let’s consider the program and output first#include <stdio.h> int myFunction() { static int var=0; var+=1...
(1) a static local variable defines its lifetime in the function as the entire source, but its scope remains the same as that of the automatic variable, and can only be used within the function defining the variable. After exiting the function, you cannot use it even though it still ...
Static Variables in C - By default, a C variable is classified as an auto storage type. A static variable is useful when you want to preserve a certain value between calls to different functions. Static variables are also used to store data that should b

3.具有内部链接的静态变量(static variable with internal linkage) 普通的外部变量可以被程序的任一文件所包含的函数使用,而具有内部链接的静态变量只可以被与它在同一个文件中的函数使用。 1//举个例子2文件1:a.c3intmoney =10;4staticwife =1;5intmain()6{7money++;8printf("wife = %d\n",wife);9}...
