Answer:
The C's malloc and free functions and the C++'s new and delete operators execute similar operations but in different ways and return results.
Explanation:
- The new and delete operators return a fully typed pointer while the malloc and free functions return a void pointer.
-The new and delete operators do not return a null value on failure but the malloc/free functions do.
- The new/delete operator memory is allocated from free store while the malloc/free functions allocate from heap.
- The new/delete operators can add a new memory allocator to help with low memory but the malloc/free functions can't.
- The compiler calculates the size of the new/delete operator array while the malloc/free functions manually calculate array size as specified.

<h2>Upgrading and retraining are mandatory to move along with the world.</h2>
Explanation:
Let us understand the term deeply,
Upgrading - Updating yourself with the latest
Retraining - learning new skills
Let me give you a real-life example which is nothing but "mobiles". If you are not updated then:
- you will sit with mobile to make calls and
- do money transactions only by stepping into the bank,
- connect with people only through calls or directly visiting them,
- distance break up the relationship,
- booking tickets in classical way, etc.
These could be done in one touch if you have latest mobile with necessary applications.
In a similar way, we need to get retrained to get to learn new skills, technologies so that we can do our job the best, to be on track, be productive, convert your valuable knowledge in terms of money, to be peaceful in day today transactions, etc.
