When you call new will it internally call delete in c plus plus?

No. Calling new returns a pointer to allocated memory. If you re-use a pointer to store the return value, then you must release the memory that it previously pointed at, either by deleting the pointer, or by maintaining a separate pointer to the original memory. Calling new will not release the current memory for you.

What will happen if you allocate memory using new and free it using free or allocate sing calloc and free it using delete?
The C++ new uses malloc internally to allocate memory and the C++ delete uses free internally to revoke memory. However, they are not interchangeable and so memory allocated with new MUST be revoked with delete. If you mix them up, you will have a memory leak! Haya.

Are new and delete operators in c plus plus related to flush?
The new and delete operators in C++ are not related to flush. New is used to allocate memory, while delete is used to deallocate memory. Flush is a library concept that allows you to ensure that IO is completed, and not buffered, before proceeding to the next step.

Difference between new and delete in c plus plus?
New creates objects. Delete deletes objects. eg - int *x = new int; // Give me a new int eg - delete x; // Delete the int that was created These functions are useful because they allow you to allocate as much memory as you need (eg ask the user for how many numbers do they want to type in, allocate that many ints and then loop through and store the values). Note that there are two other operators, new[] and delete[] that are used for creating/deleting arrays. eg - int *x = new int[5]; // Give me 5 new ints eg - delete[] x; // Delete the 5 ints If you mix and match the different operators(eg new[] with delete) you may end up with memory leaks - delete only expects one object, so if you give it 10 objects created by new[] then it will only delete one.

It depends, especially if you are going to use C++.If you allocated the variable using the malloc call or any of its derivatives you must use the corresponding 'free' subroutine call to delete them.If you use the more modern C++ 'new' operator, then use the 'delete' operator to remove the memory dynamically in the program.
