No,we shouldnot use 'free' to free memory assigned by new.
It causes memory leak and sometimes hanging of the system

Answer / nishikant sahu
Yes you can but not recommend, b'c some time when you class
hold the heap memory it can't be free by "Free" b'c of no
constructor call happening via "Free" and you get the memory
leak. so use New/ delete or malloc/free pair.

Answer / guest
Yes we can use free which was assigned by new.but in this
case no destrctor will be called as free doesn't call this.
So it is recommended that we should not use free if we
allcoate the memory using new.

Answer / krishnarao panchadi
Syntactically we can use "free" in place of "delete". But
semantically it is senseless as it wont call the destructor.
Note that, deallocating is not the only purpose of
using "delete". The destructor should also be called if you
call the constructor(while creating the object).
Failing to call "delete" may lead to system crash.
Using "free" wont call the desturctor.

How to implement flags?
Assume an array of structure is in order by studentID field of the record, where student IDs go from 101 to 500. Write the most efficient pseudocode algorithm you can to find the record with a specific studentID if every single student ID from 101 to 500 is used and the array has 400 elements. Write the most efficient pseudocode algorithm you can to find a record with a studentID near the end of the IDs, say in the range from 450 to 500, if not every single student ID in the range of 101 to 500 is used and the array size is only 300
