So I've been working on this all day and it almost works, but when I compile it with GCC it gives me three error messages:
arrayClassDriver.cpp:11: error: 'arrayClass' was not declared in this scope
arrayClassDriver.cpp:11: error: expected ';' before 'test'
arrayClassDriver.cpp:13: error: 'test' was not declared in this scope
Obviously it thinks arrayClass (the class instance) is a variable. How can I fix this?
Here's my definition of my class:
//Pre and Post Conditions
//arrayClass(int inputSize);
//Pre: A user defined int inputSize.
//Post: An array with size = inputSize has been created.
//~arrayClass();
//Pre: A dynamically created array.
//Post: The array has been deleted.
//void display();
//Pre: A dynamically created array.
//Post: List of all the values from the array.
//void resize(int newSize);
//Pre: A dynamically created array.
//Post: An array with the new size defined by the user.
//int& operator[](int location);
//Pre: None.
//Post: An operator which allows the programmer to access the array.
//int findMaxValue();
//Pre: A dynamically created array.
//Post: The max value of the array is returned.
//int findMinValue();
//Pre: A dynamically created array.
//Post: The min value of the array is returned.
//void sort();
//Pre: A dynamically created array.
//Post: A sorted array ready to be searched.
//int search(int key);
//Pre: A dynamically created array.
//Post: The sought value is returned.
#ifndef ARRAYCLASS_H
#define ARRAYCLASS_H
#include <iostream>
namespace arrayClass_Namespace
{
class arrayClass
{
private:
int *arr;
const static int MAX_SIZE = 1000;
int size;
public:
//Constructor
arrayClass(int inputSize);
//Destructor
~arrayClass();
void display() const;
void resize(int newSize);
int& operator[](int);
int findMaxValue();
int findMinValue();
void sort();
int search(int key);
};
}
#endif
Here's my implementation (I know I haven't written the code for the sort or the search yet):
#include <cassert>
#include "arrayClass.h"
arrayClass_Namespace::arrayClass::arrayClass(int inputSize)
{
assert(inputSize < MAX_SIZE);
size = inputSize;
arr = new int[size];
for (int index = 0; index < size; index++)
{
arr[index] = 0;
}
}
arrayCLass_Namespace::arrayClass::~arrayClass()
{
delete[] arr;
arr = NULL;
}
void arrayClass_Namespace::arrayClass::display() const
{
std::cout << "\nIndex" << "\t" << "Value";
for (int index = 0; index < size; index++)
{
std::cout << index << "\t" << arr[index];
}
}
int& arrayClass_Namespace::arrayClass::operator[](int location)
{
assert(0 <= location && location < size);
return arr[location];
}
int arrayClass_Namespace::arrayClass::findMaxValue()
{
int max = 0;
for (int index = 0; index < size; index++)
{
if (max < arr[index])
{
max = arr[index];
}
else if (max > arr[index])
{
max = max;
}
}
}
int arrayClass_Namespace::arrayClass::findMinValue()
{
int min = arr[1];
for (int index = 0; index < size; index++)
{
if (min > arr[index])
{
min = arr[index];
}
else if (min < arr[index])
{
min = min;
}
}
}
void arrayClass_Namespace::arrayClass::sort()
{
}
int arrayClass_Namespace::arrayClass::search(int key)
{
}
And finally, here's my driver (still need to add a few things, but I wanted to do this first):
#include <cstdlib>
#include "arrayClass.h"
int main()
{
arrayClass test(10);
test.display();
return EXIT_SUCCESS;
}
Besides that, am I using the display member function correctly? It's been a little while since I've worked with classes, so any help is greatly appreciated.
Thanks in advance!

You forgot to specify namespace for arrayClass in this statement
arrayClass test(10);
Shall be
arrayClass_Namespace::arrayClass test(10);
Or you could write
#include <cstdlib>
#include "arrayClass.h"
int main()
{
using arrayClass_Namespace::arrayClass;
arrayClass test(10);
test.display();
return EXIT_SUCCESS;
}
