C++ examples for template:template class
Implements stack class as a template, member functions are defined outside the class
#include <iostream> using namespace std; const int MAX = 100; template <class Type> class Stack/* ww w.j a v a2 s . c o m*/ { private: Type st[MAX]; //stack: array of any type int top; //number of top of stack public: Stack(); //constructor void push(Type var); //put number on stack Type pop(); //take number off stack }; template<class Type> Stack<Type>::Stack() //constructor { top = -1; } template<class Type> void Stack<Type>::push(Type var) //put number on stack { st[++top] = var; } template<class Type> Type Stack<Type>::pop() //take number off stack { return st[top--]; } int main() { Stack<float> s1; //s1 is object of class Stack<float> s1.push(1111.1F); //push 3 floats, pop 3 floats s1.push(2222.2F); s1.push(3333.3F); cout << "1: " << s1.pop() << endl; cout << "2: " << s1.pop() << endl; cout << "3: " << s1.pop() << endl; Stack<long> s2; //s2 is object of class Stack<long> s2.push(123123123L); //push 3 longs, pop 3 longs s2.push(234234234L); s2.push(345345345L); cout << "1: " << s2.pop() << endl; cout << "2: " << s2.pop() << endl; cout << "3: " << s2.pop() << endl; return 0; }
