delete []
Author
When using delete, what possible errors could you get? I try to free some memory using delete and it gives me an assert error "Damage after Normal block #1641 : 00DFAAD0" (the wording may be a bit diff but the numbers are the same). The memory pointer is the correct pointer to the memory I am trying to free. I output the address to a file directly after allocation and then again just before I free it and it is the same pointer all three times (in the assert as well). Any suggestions?

You''re overwriting the bounds of an array, and buggering up memory after it.
E.g.
HTTP 500 x4
E.g.
int* pArray = new int[4];for(int i=0; i<=4; ++i) pArray[i] = i*2; HTTP 500 x4
>>I output the address to a file directly after allocation and then again just before I free it and it is the same pointer all three times (in the assert as well).<<
drop some code so we can see.
by any chance do you free the memory in another function?
also what did you create it with? new? or malloc/calloc/realloc?
is the memory in question an array or single entity?
(ie. int *intPtr = new int[10] or int *intPtr = new int)

I was reading data from a file into the array of WORDs and it was overflowing. I was using fscanf(). What % thing should I use to read in a short (or a WORD)

There doesn''t appear to be one in the MSDN.
You could just do this:
HTH
HTTP 500 x1
You could just do this:
char szBuffer[32]WORD wVal;fscanf("%31s",szBuffer); // I think thats rightwVal = (WORD)atoi(szBuffer); HTH
HTTP 500 x1
(note: show code)
since you''re using C you should be using free( ) not delete[] (gathering from what you told me). also you can use %i or %d for short i believe. and make the array bigger

@Alpha_ProgDes: Sorry, I thought I explained it well enough without showing code.
@Evil Bill: Thanks. That is what I am going to do now except I am just inputting it straight into an int and then typecasting it to a word.

%i: "Decimal, hexadecimal, or octal integer. Pointer to int."
%d: "Decimal integer. Pointer to int."
Greg K: D''oh! Sorry, me being blonde again.
