You didn’t find a definitive answer because there isn’t one. It’s up to the author of the program to decide what exit codes they wish to use. Standard C only says that exit(0) or exit(EXIT_SUCCESS) indicate that the program is successful, and that exit(EXIT_FAILURE) indicates an error of some kind. (Returning a value from main is equivalent to calling exit with that value.) Most common … Read more
If you are on Linux, try running valgrind. You just compile with -g (with gcc), and then run your program with valgrind in front: Unlike the GCC solutions, which tell you when the segfault occurs, valgrind usually tells you exactly when the first memory corruption occurs, so you can catch the problem much closer to its source. PS. It rhymes … Read more
Bus errors are rare nowadays on x86 and occur when your processor cannot even attempt the memory access requested, typically: using a processor instruction with an address that does not satisfy its alignment requirements. Segmentation faults occur when accessing memory which does not belong to your process. They are very common and are typically the … Read more

So I’m getting a segmentation fault error in the beginning of the code. I’ve tried running some tests at the different points and the error seems to be when i allocate memory for the array. Ive just started learning about heap and stack memory so I’m not really sure if I’m doing something wrong there. … Read more
You have a std::vector called bigDeck and in DealQCard you attempt to access its 0th element, despite the fact it has no elements. Did you mean to put some cards in bigDeck?
You’ve exceeded your stack space given by the OS. If you need more memory, the easiest way is to allocate it dynamically: However, std::vector is preferred in this context, because the above requires you to free the memory by hand. If you can use C++11, you can possibly save some fraction of time by using unique_ptr array specialization, too: Both of … Read more
This declaration: would occupy 8 * 1000 * 1000000 bytes on a typical x86 system. This is about 7.45 GB. Chances are your system is running out of memory when trying to execute your code, which results in a segmentation fault.
