So can i allocate memory like <br />
<br />
char var[sizeof(newitem)+30] and not care about deleting it since its gone when out of scope?

So can i allocate memory like

char var[sizeof(newitem)+30] and not care about deleting it since its gone when out of scope?

<div>
&gt;&gt; char var[sizeof(newitem)+30]<br />
<br />
That's ok.<br />
<br />
&gt;&gt;&nbsp;and not care about deleting it since its gone when out of scope? <br />
<br />
Exactly.<br />
<br />
<br />
But you won't be able to change the size of the buffer at run time. It's fixed at compile time to sizeof(newitem)+30 chars.

Hi,<br />
I come from java background so this is confusing for me. When allocating dynamic memory in cplusplus what is the difference between allocating memory for char array using char var[40] and char* var = new char[40]?<br />
<br />
How do I delete/free the allocated memory of char arrays in both forms?<br />
<br />
thanks in advance.<br />

Difference betweeen char[] and char* = new char[]

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.
