Templates and Static variables in C++
In this tutorial, we will be discussing a program to understand templates and static variables in C++.
In case of function and class templates, each instance of the templates has its own local copy of the variables.
Example
#include <iostream>
using namespace std;
template <typename T>
void fun(const T& x){
static int i = 10;
cout << ++i;
return ;
}
int main(){
fun<int>(1); //printing 11
cout << endl;
fun<int>(2); //printing 12
cout << endl;
fun<double>(1.1); //printing 11 again
cout << endl;
getchar();
return 0;
}Output
11 12 11
