C++ "Function" was not declared in this scope
<p>I was given an assignment in class to:</p>

<blockquote>
  <p>Write a program that creates and manages arrays by the use of pointers. Your main program should interact with pointers/arrays only through various functions. These functions will then limit the use of array to their proper handling. For example these functions will eliminate the possibility of overstepping the boundaries of an array.</p>
</blockquote>

<p>So far I have written the program and fixed most of the errors, however no matter what I try I keep getting "function not declared in this scope" errors. The program includes the following files: <code>main.cpp</code> <code>MyArray.cpp</code> and <code>MyArray.h</code></p>



<h3>main.cpp</h3>

<pre class="lang-cpp prettyprint-override"><code>#include &lt;iostream&gt;

    int *Array1, *Array2;
    int Array1Size(10), Array2Size(10);
    int Array1Value(0), Array2Value(0);

    cout &lt;&lt; "Enter Size and Initial value for Array1: ";

    cin &gt;&gt; Array1Size &gt;&gt; Array1Value;

    cout &lt;&lt; "Enter Size and Initial value for Array2: ";

    cin &gt;&gt; Array2Size &gt;&gt; Array2Value;

    CreateArray(Array1, Array1Size);
    InitArray(Array1, Array1Size, Array1Value);

    CreateArray(Array2, Array2Size);
    InitArray(Array2, Array2Size, Array2Value);

    cout &lt;&lt; "Printing Array1:" &lt;&lt; endl;
    PrintArray(Array1, Array1Size);
    cout &lt;&lt; endl;
    cout &lt;&lt; "Printing Array2:" &lt;&lt; endl;
    PrintArray(Array2, Array2Size);
    cout &lt;&lt; endl;

    if(CopyArray(Array1, Array1Size, Array2, Array2Size)) {
        cout &lt;&lt; "Copy was successful" &lt;&lt; endl;
    } else {
        cout &lt;&lt; "Copy was not successful" &lt;&lt; endl;
    }

    cout &lt;&lt; "Printing Array1:" &lt;&lt; endl;

    PrintArray(Array1, Array1Size);

    cout &lt;&lt; endl;

    EnterArray(Array1, Array1Size);

    // MergeArray(Array1, Array1Size, Array2, Array2Size);

    cout &lt;&lt; "Printing Array1:" &lt;&lt; endl;

<p>The errors I get resemble this: <code>main.cpp:'LineNumber': error. 'Every Function in MyArray.cpp' was not declared in this scope</code> (I would copy paste the exact errors but I can't copy paste from the terminal I'm using to connect to the remote host were I compile my code)</p>

<p><br/>I've been trying to fix this problem for hours and I can't figure it out, I've even looked at other Stack posts like <a href="http://stackoverflow.com/questions/6283168/foo-was-not-declared-in-this-scope-c">'foo' was not declared in this scope c++</a>
<br/>Any help would be much appreciated, thank you.</p>

<p>Also I did not write main.cpp, it was given with the assignment.</p>
