Using malloc is giving me more memory than expected?

Question

I\'m trying to get to grips with malloc, and so far I\'m mostly getting unexpected results when testing and playing around with it.

int main(int arg         


        

Answer 1

Undefined behavior doesn't mean "guaranteed segmentation fault"; it may work in some cases.

There is no way of knowing how far beyond an array's bounds you can go before you finally crash; even dereferencing one element beyond a boundary is undefined behavior.

Also: if malloc succeeds, it will allocate at least as much space as you requested, possibly more.
