As mentioned in the question, I have a segfault in the implementation of Conway's game of life in gtkmm that I am working on.
It can be found here: https://github.com/sakekasi/game-of-life
The backtrace of the error can be found here: https://gist.github.com/3505525
When I insert print statements in cells_get or create_updated grid, it starts printing, doesn't produce a segfault and goes on forever without doing anything.
create_updated_grid is accessing cells off the edge of the grid. It's calling things like cells_get(i+1,j).
You need to change your out-of-bounds checks in cells_get to >=, not >.

So I'm brand new to c++ and just started the beginner class. The professor has given us the exact prompt to put into the program and I am still receiving an error. I have checked over and over for any small flaws such as spacing or random ";" that a lot of people seem to do, but still no results. Can anyone see anything wrong with what I have down?
Remove asterisk (*) right below "//Purpose of this program ..." and try it again.

Hello there I am a realative newbie when it comes to using different "commands" in order to achieve things so I was wondering if any of you know a way to bind a key to do a certain task anywhere in the programme ,so I would be able to display a function for example and after the display finishes the programme carries on normally like nothing happened and then that same key on any other push would still do the display . Thanks in advance
Plain C++ does not have any concept of "key binding". The platform (e.g., the operating system) has this knowledge and it provides some libraries to handle it. So, you must provide more information about the operating system, or use a cross-platform library like Qt.

This may be a repost but I thought I might open a topic myself since nothing really answers my questions so far.
Okay, so if I attach a webcam to a robot, is it possible to use the webcam to determine which way the robot is moving (Forward, back, turning left, turning right) because I am doing a project that requires me to detect alignment of the robot down a hallway using a webcam.
Is this possible?
You can do this with optical flow. It is implemented in OpenCV

Suppose I need to recognize single word or even a letter. So I need not find rows of text, deskew them, split into words...
How to run recognition process with these exclusions?
I see only was to set rectangle, but this also does not mean that all steps won't be performed.
Setting rectangle and page segmentation mode should do.

Note:Program include lots of functions.
Thanks!
Is it true?
