Question

Need help with my programming. I don't want it rewritten, I just want help correcting any errors and please let me know what I am doing wrong.

#include <stack>
#include <string>
#include <iostream>

using namespace std;

class Safestack {
   stack<string> s;
   string top (){

       public:
try
       {
            stack<int> values;
            string input;
           int c=0;
};

   main()
{
   SafeStack s;
   s.push(string);
   cout<<s.top();
   s.pop();
   s.top(); // will give an error

}

Explanation / Answer

The push() function is used to populate the data into the stack defined.
The function Push() is given below,

Push
----
// max is maximum number of elements
// stack[] is the array for stack

void stack::push(int y) //Push Operation
{
if(t<max)
{
t=t+1;
stack[t]=y;
}
else
cout<<endl<<"stack overflows..."<<endl;
}

The pop function is used to remove the data from the stack.

POP
-----

// max is maximum number of elements
// stack[] is the array for stack
void stack::pop() //Pop Operation
{
int item;
if(t>=0)
{
t=t-1;
item=stack[t+1];
cout<<endl<<"popped item >>"<<item<<endl;
}
else
cout<<endl<<"stack underflows"<<endl;
}

The try.. catch is used for exception handling. It is not mandatory to use the try .. catch in the program , it only enhances the error handling.
The format of try

---
try {
// code here
}
catch (int param) { cout << "int exception"; }
catch (char param) { cout << "char exception"; }
catch (...) { cout << "default exception"; }
