If you didn't allocate memory dinamically (with new) you don't need to free it.

<div>
&gt;&gt;&gt;&gt; after using it I want to free the memory. 
 
The allocation of the pointer variable itself (4 bytes or 8 bytes depending on compiler) &nbsp;will be allocated at the stack and doesn't need to get freed. The storage automatically was freed when the variable goes out of scope (after the ending } of the current block). 
 
&gt;&gt;&gt;&gt;&nbsp;If you didn't allocate memory dinamically (with new) you don't need to free it. 
 
To add to above information: 
 
if you assigned a pointer value to the variable where you did *not* made a new before, you may *not* call delete or the program will crash. 
 
(A) 
// assign a literal 
const TCHAR* tes = _T(&quot;Hello World&quot;); 
 
... 
delete []tes; &nbsp;// error, will crash 
 
 
(B) 
{ 
&nbsp; &nbsp;const TCHAR* tes =NULL; 
&nbsp; &nbsp;CString &nbsp;s = &quot;Hello World&quot;; 
 
&nbsp; &nbsp;tes = (LPCTSTR) s; 
 
&nbsp; &nbsp;delete []tes; &nbsp; // if it compiles it won't crash here .... 
} 
// ... but here, when the &nbsp;CString &nbsp;s goes out of scope and the buffer was deleted once more 
 
(C) 
&nbsp; &nbsp;const TCHAR* tes = new TCHAR[32]; 
&nbsp; &nbsp;tcscpy((LPTSTR)tes, _T(&quot;Hello World&quot;)); 
&nbsp; &nbsp;... 
&nbsp; &nbsp;delete []tes; &nbsp;// ok 
 
 
Note, the cast to LPTSTR was necessary because tes was defined as const. 
 
 
 
 

</div>

<div>
(A) 
// assign a literal 
const TCHAR* tes = _T(&quot;Hello World&quot;); 
 
... 
delete []tes; &nbsp;// error, will crash 
 
This is my case 
 
If I don't free the memory space explicitly then it will do it automatically 
 
that is what you are saying.

<div>
The line 
 
const TCHAR* tes = _T(&quot;Hello World&quot;); 
 
doesn't allocate any memory so you have not to free it (neither you nor the system).

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

Editors IDEs

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. It features tools for developing and debugging C++ code, especially code written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework. Many applications require redistributable Visual C++ packages to function correctly and are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once

Visual C++.NET

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
