The Problems: Bad pointers, writing of the end of allocated memory, memory leaks. C++ gives you lots of flexibility when it comes to memory management. You are allowed to allocate and deallocate memory and directly manipulate pointers. Flexibility comes with a cost. Because the language allows you to allocate memory, you can screw up the allocations. Similarly you can screw up the deallocation and use of pointers. Since there are no built-in safety checks in C++ what do you do to protect your code?
