In the function: vectorfactorize why the 2nd argument is passed by address?
It’s a vector and hence dynamic , then why pass by address??
Prime Factorisation of a number
vector is non-array, non-reference, and non-pointer - it is being passed by value,
and hence it will call copy-constructor. So, you must use vector& (preferably with const , if function isn’t modifying it) to pass it as a reference. vector would be passed by value in this.
