13.1 INTRODUCTION A template is an abstract recipe for producing concrete code. Templates can be used to produce functions and classes. The compiler uses the template to generate the code for various functions or classes, the way you would use a cookie cutter to generate cookies from various types of dough. The actual functions or classes generated by the template are called instances of that template. The same template can be used to generate many different instances. This is done by means of template parameters which work much the same way for templates as ordinary parameters work for ordinary functions. But whereas ordinary parameters are place holders for objects, template parameters are place holders for types and classes. The facility that C++ provides for instantiating templates is one of its major features and one that distinguishes it from most other programming languages. As a mechanism for automatic code generation, it allows for substantial improvements in programming efficiency. 13.2 FUNCTION TEMPLATES In many sorting algorithms, we need to interchange a pair of elements. This simple task is often done by a separate function. For example, the following function swaps integers:

void swap(int& m, int& n) { int temp = m; m = n; n = temp; } If, however, we were sorting string objects, then we would need a different function: void swap(string& s1, string& s2) { string temp = s1; s1 = s2; s2 = temp; }

These two functions do the same thing. Their only difference is the type of objects they swap. We can avoid this redundancy by replacing both functions with a function template: EXAMPLE 13.1 The swap Function Template
template <class T> void swap(T& x, T& y) { T temp = x; x = y; y = temp; }

TEMPLATES AND ITERATORS
The symbol T is called a type parameter. It is simply a place holder that is replaced by an actual type or class when the function is invoked.
A function template is declared the same way as an ordinary function, except that it is preceded by the specification
template <class T>
and the type parameter T may be used in place of ordinary types within the function definition. The use of the word class here means any type. More generally, a template may have several type parameters, specified like this:
template <class T, class U, class V>
Function templates are called the same way ordinary functions are called:
int m = 22, n = 66; swap(m, n); string s1 = "John Adams", s2 = "James Madison"; swap(s1, s2); Rational x(22/7), y(-3); swap(x, y);
For each call, the compiler generates the complete function, replacing the type parameter with the type or class to which the arguments belong. So the call swap(m,n) generates the integer swap function shown above, and the call swap(s1, s2) generates the swap function for string objects. Function templates are a direct generalization of function overloading. We could have written several overloaded versions of the swap function, one for each type that we thought we might need. The single swap function template serves the same purpose. But it is an improvement in two ways. It only has to be written once to cover all the different types that might be used with it. And we don t have to decide in advance which types we will use with it; any type or class can be substituted for the type parameter T. Function templates share source code among structurally similar families of functions. EXAMPLE 13.2 The Bubble Sort Template
This is the Bubble Sort (Example 6.13 on page 134) and a print function for vectors of any base type. template<class T> void sort(T* v, int n) { for (int i = 1; i < n; i++) for (int j = 0; j < n-i; j++) if (v[j] > v[j+1]) swap(v[j], v[j+1]); }
template<class T> void print(T* v, int n) { for (int i = 0; i < n; i++) cout << " " << v[i]; cout << endl; } int main() { short a[9] = {55, 33, 88, 11, 44, 99, 77, 22, 66};
