Display stack Note: We can't traverse (iterate) through stack. Stacks are a type of container adaptor, specifically designed to operate in a LIFO context (last-in first-out), where elements are inserted and extracted only from one end of the container. Elements are pushed/popped from the "back" of the specific container, which is known as the top of the stack. It is not intended for stack to show this behavior, for this we have other containers like vector. In case of vector use push_back() and pop_back() functions. reverser_iterator class is called in below code to traverse the vector in reverse orde. */ #include "iostream" #include "vector" #include "stdlib.h" // used for exit(0) using namespace std; class StackUsingVectorSTL{ public: vector<int> pushToStack(vector<int>); vector<int> popFromStack(vector<int>); void displayStack(vector<int>); };

Function Template in C++
/* Title: Function template in C++ Author: Pavan R Jaiswal
In C++, function templates are functions that serve as a pattern for creating other similar functions. \ The basic idea behind function templates is to create a function without having to specify the exact type(s) of some or all of the variables. Instead, we define the function using placeholder types, called template type parameters. Problem Statement: Use function template to check greater number from given two numbers */ #include "iostream" using namespace std; class FunctionTemplate{ public: template <typename type> //keyword "typename" can be replaced by keyword "class" type greaterNumber(type tNum1, type tNum2){ return (tNum1>tNum2)?tNum1:tNum2; } };
