A segmentation fault is a kind of error that happens when a program makes an attempt to entry reminiscence that it’s not allowed to entry. This will occur for quite a lot of causes, akin to when a program tries to entry reminiscence that has been freed, or when it tries to entry reminiscence that’s exterior of the bounds of an array. Segmentation faults might be troublesome to debug, as they are often brought on by quite a lot of components.
There are a variety of issues that may be carried out to keep away from segmentation faults. One vital step is to ensure that all pointers are legitimate earlier than they’re used. This may be carried out by checking that the pointer isn’t null, and that it factors to a legitimate reminiscence location. Moreover, it is very important ensure that all arrays are correctly bounded, and that this system doesn’t try and entry reminiscence exterior of the bounds of the array.
