Templates are the foundation of generic programming, which involves writing code in a way that is independent of any particular type.

A template is a blueprint or formula for creating a generic class or a function. The library containers like iterators and algorithms are examples of generic programming and have been developed using template concept.

There is a single definition of each container, such as vector, but we can define many different kinds of vectors for example, vector <int> or vector <string>..

Function Template :

The general form of a template function definition is shown here:

template <class type> ret-type func-name(parameter list)

{
// body of function
}

---

Class Template :

Just as we can define function templates, we can also define class templates. The general form of a generic class declaration is shown here:

template <class type> class class-name

{
.
.
.
}

Below is the source code for C++ Program to show Example of Static member variable of template class which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C++ Program to show Example of Static member variable of template class  */

#include <iostream>

using namespace std;

template <class T> 
class XYZ
{
public:
    void putPri();
    static T ipub;
private:
    static T ipri;
};

template <class T> 
void XYZ<T>::putPri()
{
    cout << ipri++ << endl;
}

// Static variable initialization:
template <class T> T XYZ<T>::ipub = 1;
template <class T> T XYZ<T>::ipri = 1.2;

int main()
{
    XYZ<int> aaa;
    XYZ<float> bbb;

    aaa.putPri();
    cout << aaa.ipub << endl;
    bbb.putPri();
    return 0;
}

OUTPUT : :

---

/*  C++ Program to show Example of Static member variable of template class  */

1
1
1.2

Process returned 0
