I need to combine both these C++ programs I have pasted below into one program.

#include

#define MAX 1000

using namespace std;

class Stack{

int top;

public:

int a[MAX]; // Max size of Stack

Stack(){

top = -1;

}

//top is initialized to -1 to check the emptiness of the stack

bool push(int x);

int pop();

bool isEmpty();

int peek();

};

int Stack::peek(){

return a[top];

}

bool Stack::push(int x){

if (top >= MAX){

cout << "Stack is full it is Overflowing";

return false;

}

else{

a[++top] = x;

return true;

}

}

int Stack::pop(){

if (top < 0)

return 0;

else{

int x = a[top--];

return x;

}

}

//Checks the stack if its empty or not

bool Stack::isEmpty(){

return (top < 0);

}

// checks for pairs

bool Pair(char opening,char closing){

if(opening == '(' && closing == ')') return true;

else if(opening == '{' && closing == '}') return true;

else if(opening == '[' && closing == ']') return true;

return false;

}

bool Balanced(string exp){

Stack S;

for(int i =0;i

if(exp[i] == '(' || exp[i] == '{' || exp[i] == '[')

S.push(exp[i]);

else if(exp[i] == ')' || exp[i] == '}' || exp[i] == ']'){

if(S.isEmpty() || !Pair(S.peek(),exp[i]))

return false;

else

S.pop();

}

}

return S.isEmpty() ? true:false;

}
