template is used for creating generic functions as well as data members.

A template parameter is a special kind of parameter that can be used to pass a type as argument: just like regular function parameters can be used to pass values to a function, template parameters allow to pass also types to a function. These function templates can use these parameters as if they were any other regular type.

The format for declaring function templates with type parameters is:

template <class identifier> function_declaration;
template <typename identifier> function_declaration;


lets take an example to understand TAMPLATES

#include <iostream>
using namespace std;

template <class T>
T GetMax (T a, T b) {
  T result;
  result = (a>b)? a : b;
  return (result);
}

int main () {
  int i=5, j=6, k;
  long l=10, m=5, n;
  k=GetMax<int>(i,j);
  n=GetMax<long>(l,m);
  cout << k << endl;
  cout << n << endl;
  return 0;
}

A template is a function that is defined without template parameters, being parameters that have an undefined type. The logic of the function must be executable for all possible data types e.g. using standard operators.

The template can then be invokes for a speciic set of parameters, by defining the data types for which we are calling the function

One obvious example may be max function relying on the use of a > operators for whatever data types are passed to it
