char array memory collection

[ivan47]

I'm creating a char array in the following way, and don't know whether it is being collected or not. I know I have a memory leak somewhere in my code ("ps wwvg | grep myapplication" shows memory usage) , but I'm not sure if it's being caused by the following:

 
void example()
{
char array[50000]="";
}
 

That's basically it. Normally I would do something like

char * array = new char[5000];

in which case I would know to delete it, but I can't find any info on the first way of creating/deleting an array.

In your first example the array is a so called 'automatic' variable, i.e. it resides on
the stack and is 'automatically' ripped from existence when the function returns.

Also, be careful of large stack memory usage. Some systems limit stack to as little as 4K without negotiating with a SysAdmin for more.

Prefer the heap to the stack.
