In dynamic memory allocation if we will not deallocate memory using delete operator in c++ then what will happen ???

Question

C++

Answer 1

Thanks to all

Answer 2

Then you have memory leak in your program, in C++ use Smart pointers like std::shared_ptr instead of raw pointers.

Answer 3

If you deleted the pointer to the memory somehow then that memory will stay as allocated and will be inaccessible causing a memory leak. This leak is fixed when the progam exits or a system reboots.

As per your question, the memory remains allocated until you delete it or the process finishes and causes memory leak.
