I've been trying to debug this program for a while now and can't quite see where this error is originating from. BUT, when I run it through our Ubuntu student server, I get this crazy error.
Every time I run this program on NetBeans, I have no issue. The idea of these sort of questions is to teach the funementals, and HOW and WHY certain things work, they may not be the easiest or most efficient way of doing things (the type of stack-smash you're getting is still causing problems in major systems today because programmers forget to check sizes etc).So I'm working on a program in my Programming I class and we were assigned to create a program that will check to see if a routing number from a bank is valid. However, if this is for school or a uni assignment, make sure you've been taught to do it this way, because sometimes you can be deducted marks for 'rushing ahead'. Whilst it is a C++ page it covers stuff that is common for both C and C++ (as C++ is based on C)Īlso, as Pearsonartphoto said, you can just declare your array as char message = "Hello, World!"
so you'll need to declare an array of 14 characters.įor a bit more in-depth explanation on working with string and the null-character, i suggest this page.
BLENDER STACK SMASHING DETECTED PLUS
But how much more? enough to fit "Hello, world!" PLUS one more for the null-terminator character '\0', which determines the end of the string. So, you'll need to give your message array more space. As such you are overwriting memory that isn't part of your array.įor reference, strcpy(), strcat() and most other C-string functions don't check the length of the array, they assume that you've given it enough space to work with.
Your message array is 10 characters long (0-9), but if you count "Hello, World!" (without the quotes) it is 13 characters long. Here is the program, can anyone come up with a conclusion to why it is doing this? Here is the "traceback" that occurs after the stack smash is detected. No matter what the number entered it always results in a "stack smash". I've created a file which prints Hello, world as many times at the user wants to give input.
