Searching and Looping within Stacks

I am having issues with my loop. Basically, I am trying to
- pop an item off the original stack, storing it in a temporary gumball
-then look at the color field of that temporary gumball
-if it is what you want, you have a match
-if not, push the gumball onto the temporary stack
-repeat this process until you find what you want or the original stack is empty
-put all the items from the temp stack back onto the original stack in its original order

I AM HAVING PROBLEMS WITH MY SYNTAX, AND WHICH LOOPS TO USE TO GET THIS TO WORK THE WAY IT IS INTENDED TO. Any Suggestions???

The loop I am having problems with right now is under my "case e" for Eat:

int main():


#include <iostream>
#include "Stack.h"
#include "Gumball.h"

using namespace std;

int main()
{
Stack s, gumballStack;
Gumball g, temp;
char choice;
bool choice_flag = true;

do {
cin >> choice;
cin >> g.color;
switch(choice)
{
case 'b':
case 'B':
cout << "A" << " " << g.color << " gumball has been bought." << endl << endl;
g.counter = 0;
s.isempty();
s.push(g);
if(!s.isfull())
cout << "The gumball is" << " " << g.color << " and has been stored." << endl << endl;
else
cout << "There is no room for another gumball." << endl << endl;
break;
case 'e':
case 'E':
s.isempty();
do(s.pop()) //ERROR!
{
s.pop() = temp;
}
while(!s.isempty() && g.color != temp.color)
{
temp.counter++;
gumballStack.push(temp);
s.pop();
cout << "A gumball has been eaten." << endl << endl;
//cout << " " << g.counter << endl;
}
if(!s.isempty())
{
//cout << " " << g.counter++ << endl;
s.pop();
cout << "A gumball has been eaten." << endl << endl;
// cout << "A" << " " << g.color << " was not found." << endl << endl;
}
else
{
cout << "A" << " " << g.color << " was not found." << endl << endl;
}
while(!gumballStack.isempty())
{
//gumballStack.pop();
s.push(gumballStack.pop());
gumballStack.pop();
}
break;
case 'q':
case 'Q':
choice_flag = false;
break;
}
} while(choice_flag);

return 0;
}

Please go back and edit your post. Add [code]...[/code]around your code and then add a proper indentation. It hurts the eyes to read unintented code...

how do i edit my post? I am new on this site and cant find the editing button

I reposted it, just so I dont waste time trying to edit.
