char * pointers

[Blessman11]

hi

How can char * pointers be deleted? I've tried this code but it doesn't work. All it does is return the debug assertion error

//current level name is a char * pointer

if (current_level_name)
	delete [] current_level_name; //clear array

The delete statement looks fine.

How is current_level_name being allocated?

P.S. It's safe to pass NULL to delete, so you don't need the if statement in this case.

You should set the pointer to NULL after deleting it in order to clear the data.

char *array = new char[64];
array = "Array: I'M ALIVE!!! \n";
if (array) printf(array);
delete[] array;
array = NULL;
if (!array) printf("*Silence*");

current level name is being allocated as:
char * current_level_name;

And the way I pass data to it is through coping another pointer in a function

void GameLevel:: Initialize(char * cnewname)
{
//this is how I'm passing data to it
current_level_name = cnewname;
....
return;
}

does delete have to be called only when new is present?

[Blessman11]

problem solved: turns out I had a destructor issue, apparently a destructor shouldn't be called manually since C++ handles it when it goes out of scope

does delete have to be called only when new is present?

As you worked out, delete should only be called if the object was allocated with new.

You were passing the address of a local variable??

yh too much stress does reduce reasoning, but no I was just feeding it an array like this "message" as an argument
