Reads from a file and stores into buffer. Particularly, reads 80 characters from a file named carro.DAE and stores them into an array, then apparently overflows the fuck out of everything because he concats what was read from the buffer into another array (filling it) and then concats more shit (making it ouf of bounds). And it doesnt stop there, he stuffs that fucking string like it was thanksgiving.

Disregard the last thing I said, I suck dicks. He concats obj not buffer. Then again, no one can guarantee that all that concatenation will fit into 80 characters. It probably will work most of the time since I think strstr() scans until it reaches the null character (not the array size), but it can still probably end up crashing depending on how memory is allocated.
sum of characters<buffer size
43+obj+count<80
obj<37-count
count<37-obj
Obviously, that means count or obj cannot be greater than 37 (really 37-1 due to /0) characters in length, and even then, that means the other is 0.
Also, directives in caps and vars start and end with _. I couldn't be assed to either make sure the directives structure is constant or that it even makes fucking sense.
| Code: | ALLOCATE space for _fileHandle_ and _buffer_
READ _file_ from _fileHandle_ carro.DAE
IF error reading file
PRINT error
WHILE characters left to STORE into _buffer_ from _file_
ALLOCATE space for _title_
STORE <float_array id="_obj_-POSITION-array" count="_count_"> into _title_
IF substring in _buffer_ matches _title_
ALLOCATE start and set to
INCREMENT _start_ by one
ALLOCATE end and set to
ADD null terminating character
PRINT start
REPEAT |

it's not c++. it's c99 or above. +rep to anyone who can tell me how i know that
@aviar: i think you misunderstood (or at least didn't understand past line-by-line analysis) the whole sub-block starting with strstr

"title" is declared in the while loop and not at the beginning of the function.

| there's nothing wrong with that. the declaration occurs at the beginning of a scope so it is c89 compliant

I thought that you can't declare variables in for and while iteration statements at all? Or is it just that you can't declare a variable in the initializer part of the for loop?
From what I've read, the idea was that you are forced to allocate the variable once outside of the loop instead of allocating the same variable multiple times (even though modern compilers optimize it to shift the stack pointer only once anyway).
It might have been only recommended practice, and I mixed it up with other information (this person believes it too).

yes to the part i quoted
here, i'll give you the solution. just compile with 'gcc -std=c89 -pedantic' and see what happens 
the answer is that the '//' is not valid c89. also 'end' is not declared at the beginning of a scope

Yeah, I would've mentioned that otherwise.
Are you Ready For C99?

I hate it when people do brackets like that.
Netbeans does it too. Automatically. It makes me cringe.

I have no idea what OP is trying to do, and am unwilling to find out what it is. Simply here to see the replies and figure it out from that.

Readability doesn't suffer, so I actually prefer it. A class with 20 methods would have 20 extra lines that do absolutely nothing. It makes me cringe.
