Is bound checking in c++ language possible or not?

Question

Can we insert elements in an array more than its size?

Answer 1

Yes, you can and the compiler will quite happily allow it in both C/C++.

C/C++ always errs on the side of max performance, so it considers the costs of automatic bounds checking inserted by the compiler as too high.

This is perfectly legal C/C++:
int* p = new int[10] ;
for(int i=0; I < 1000; i++)
*(p+i) = 5+i;

But you can always roll your own bounds checking if required.
