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
Each instantiation of function template has its own copy of local static variables. 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>...
Learn about local static variables in C language, their definition, usage, and examples to understand how they differ from regular local variables.
(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 ...
I have used static variable in my Application to check the status of Logged in user, but I want to reset the value of static variable when I exit the application(Closing the application or clicking on Logout button). So how can I do this? Are any methods available to destruct the st...

Prerequisite: Storage classes in CAutomatic (auto) and static both are the keywords which are used under the storage classes, and they define the scope, lifetime, default value and memory segment of the variables.Automatic ('auto') variable...
Re: Why can't we have static variable in a struct in C Sorry for posting my program with typo, the original code is like this struct node { static int aa; int bb; }; int main() { printf("Size of node =%d", sizeof(struct node)); return 0; } Reply With Quote February 22n...
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....
