In this case set them to NULL(0). int* a = NULL; int* b = NULL; Re: memory leak in the code? Eytukan5-Jan-08 23:04 Eytukan 5-Jan-08 23:04  Who said I didn't do it? I'm a c++ programmer. class myclass { int* a; int* b; myclass() { a= NULL; b= NULL; } } OK,. what country just started work for the day ?

Anyway, I think it is pretty important to show it in the code as well. Re: memory leak in the code? George_George6-Jan-08 2:43 George_George 6-Jan-08 2:43  Hi Hamid, I am confused. My question is about whether we need to delete a or b if bad_alloc happens, does your reply has anything related to my question? regards, George Re: memory leak in the code? Hamid_RT6-Jan-08 5:16 Hamid_RT 6-Jan-08 5:16  My reply was for check does it with success or no (and my suggestion is when you want to allocate or convert use of try/catch block) and when you got error means that it doesnt allocate any thing to variable. Re: memory leak in the code? George_George6-Jan-08 20:42 George_George 6-Jan-08 20:42  Thanks Hamid, I have developed a couple of samples, which specific case do you think I need to check? regards, George Re: memory leak in the code? Hamid_RT6-Jan-08 21:10 Hamid_RT 6-Jan-08 21:10  If you check each block of your program(for exmaple is hwnd valid,etc) you can almost(not always) sure that you didnt get an exception when you run your program Re: memory leak in the code? George_George6-Jan-08 21:13 George_George 6-Jan-08 21:13  Hi Hamid, How could I check manually which block is exception safe or not? There are too many runtime errors, like out of memory or input invalid values to new which will cause bad_alloc. regards, George Re: memory leak in the code? Hamid_RT7-Jan-08 5:26 Hamid_RT 7-Jan-08 5:26  Well its simple you know some actions will be problem and you can anticipate them a short list like: (1) When you want to read a file or write a file:1-does file exist 2-does this file open with other programs 3- can you write to a file on the cd or no,does file on the floppy drive and does it write-protected or no (2) Database do you have access to database (3) when you need to a handle to a window does return value valid or its null (4) Picture does file a image file or no what was return value (5) when you want to read of internet do you have any connection to internet (6) do you have a valid pointer or its null (7) Dynamic memory,does it valid (8).... ------------------------------ After all of them you must free memory.
