mycodeschool / Stack_ArrayImplementation_OOP.cpp
Created October 8, 2013 02:44
An object oriented implementation of stack using arrays in C++.
// Stack - Object oriented implementation using arrays
#include <iostream>
using namespace std;
#define MAX_SIZE 101
class Stack
{
private:
int A[MAX_SIZE]; // array to store the stack
int top; // variable to mark the top index of stack.
/* Merge sort in C */
#include<stdio.h>
#include<stdlib.h>
// Function to Merge Arrays L and R into A.
// lefCount = number of elements in L
// rightCount = number of elements in R.

mycodeschool / InfixToPostfix.cpp
Created December 9, 2013 05:34
Infix to Postfix conversion in C++ using stack. We are assuming that both operators and operands in input will be single character.
/*
Infix to postfix conversion in C++
Input Postfix expression must be in a desired format.
Operands and operator, both must be single character.
Only '+' , '-' , '*', '/' and '$' (for exponentiation) operators are expected.
