Getting inheritance issues when trying to compile - stack

Question

I have a class called stackTester that is trying to inherit from another class stackofChars. The methods defined in stackofChars that I am trying to use in stackTester are all virtual, but when I try to use them in stackTester, I get an error
request for member which is of non-class type
Here is my stackofChars.h file:
#define STACK_OF_CHARS_H
#include "node.h"
class stackofChars
{
private:
node* m_top;
public:
//constructor for the stack, takes in no paramaters
stackofChars();
//copy constructor, takes in a referance to the original stack
stackofChars(const stackofChars& orig);
//destructor for the stack, no parameters
~stackofChars();
//destructor for the copy, takes in a referance to the copy
void operator=(const stackofChars& rhs);
//pushes the stack back and creates a new node at the stop, takes in an entry, returns nothing
virtual void push(char entry);
//deletes the top entry and pushes the stack up, takes in nothing, returns nothing
virtual void pop();
//peeks at the top entry, takes in nothing, returns a char, const because nothing is changed
virtual char peek() const;
//checks if the stack is empty, takes in no parameters, returns nothing, const because nothing is changed
virtual bool isEmpty() const;
};
#endif
Here is my stackTester.h file:
#ifndef STACK_TESTER_H
#define STACK_TESTER_H
#include "stackofChars.h"
class stackTester : public stackofChars
{
public:
stackTester();
//This will call all your test methods
void runTests();
private:
//Creates an empty stack and verifies isEmpty() returns true
void test1();
//Creates an empty stack pushes 1 value, verifies isEmpty() returns false
void test2();
//Creates an empty stack, then pushes once, pops once, and verifies isEmpty returns true
void test3();
//more test methods as needed
};
#endif
If needed, here is my stackTester.cpp file:
#include "stackTester.h"
#include "stackofChars.h"
#include <iostream>
void stackTester::test1()
{
stackofChars test();
std::cout << "Test#1: Newly created stack is empty: ";
if(test.isEmpty() == true)
{
std::cout << "Pass\n";
}
else
{
std::cout << "Fail\n";
}
}
void stackTester::test2()
{
stackofChars test();
test.push(???);
std::cout << "Test#2: Push on empty stack makes it non-empty: ";
if(test.isEmpty() == true)
{
std::cout << "Pass\n";
}
else
{
std::cout << "Fail\n";
}
}
void stackTester::test3()
{
stackofChars test();
test.push(???);
test.pop();
std::cout << "Test#3: Popping all elements makes stack empty: ";
if(test.isEmpty() == true)
{
std::cout << "Pass\n";
}
else
{
std::cout << "Fail\n";
}
}
Can someone tell me why I am getting this error?

Answer 1

stackofChars test(); is wrong.The right way to declare a class object should be: stackofChars test; or stackofChars test{};
