Bound checking in array

[luckyyyyyy]

Can over running of array lead to the catastrophic failures? If ‘Yes’ then why does not C++ provide bound checking on array operations and who is responsible to prevent array overruns?

plz explain in detail...

Yes it can be catastrophic, since you access memory you're not supposed to. For example another object might reside after the end of your array, and by writing after the end of your array, you 'silently' alter the other object.

One reason that does not provide bounds checking is speed, if you want checking, either make a class for it or use std::vector<>

You are responsible to prevent the overruns..

Yep, that's what they mean; btw are you also Naseer Ahmad?

It could happen that overrunning the array bound is exactly what your program requires in some bizarre situation. If C++ disallowed that, then you couldn't use C++ for that application and that would violate the C++ Prime Directive: There is NO programming situation that cannot be handled by C++.
