Thread: Help Please "array stack"

This is my first time on this forum. I have to make this program check for balanced parentheses. I have most of the work done. But i keep getting "cannot convert `int*' to `STACK*' for argument `1' to `void push(STACK*, int)' ". I marked where errors are in program. I believe i am not implementing the functions right please any help would be greatly appreciated. I know its probably something dumb and small.

Thanks alot in advance for any help

Code:

#include <iostream>
#include <string>
#include <fstream>
using namespace std;
char* filename;
#define MAX 300



typedef struct stack
{
int item[MAX];
int Top;
}STACK;
 void push(STACK *ps, int x)
    {
        if (ps->Top == MAX) {
            fputs("Error: stack overflow\n", stderr);
            abort();
        } else
            ps->item[ps->Top++] = x;
    }
        int pop(STACK *ps)
    {
        if (ps->Top == 0){
            fputs("Error: stack underflow\n", stderr);
            abort();
        } else
            return ps->item[--ps->Top];
    }

int main ()
{
    
   
    size_t found;
    string str, tmp;
    cout <<"Please enter the name of the file" << endl;
	filename=new char;
	cin >> filename;
	ifstream myfile(filename);
	while(!myfile.eof())
	{
    getline(myfile, tmp);
	str += tmp;
    }
  
  

 int array[300];

  found=str.find_first_of("(");
  while (found!=string::npos)
  {
    str[found]='*';
    found=str.find_first_of("(",found+1);
   push(array, 1);              //  error 
  }
found=str.find_first_of(")");
  while (found!=string::npos)
  {
    str[found]='*';
    found=str.find_first_of(")",found+1);
   pop(array, 1);              //  error 
  }
    found=str.find_first_of("{");
  while (found!=string::npos)
  {
    str[found]='*';
    found=str.find_first_of("{",found+1);
     push(array, 1);            //  error 
  }
found=str.find_first_of("}");
  while (found!=string::npos)
  {
    str[found]='*';
    found=str.find_first_of("}",found+1);
   pop(array, 1);            //  error 
  } 
    found=str.find_first_of("[");
  while (found!=string::npos)
  {
    str[found]='*';
    found=str.find_first_of("[",found+1);
    push(array, 1);             //  error 
  }
found=str.find_first_of("]");
  while (found!=string::npos)
  {
    str[found]='*';
    found=str.find_first_of("]",found+1);
   pop(array, 1);              //  error 
  }
