While declaring function pointer we should use (*identifier) while in comparators video prateek sir listed it as (&identifier).
Please clarify this doubt
Not understanding syntax of function pointers as explained in comparators video
*(star) and &(ampersand) both are used for call by reference. This means that the changes made to the variables inside the function are permanent and will reflect in int main().
We use * for arrays mostly. And we use & for single values - be it number, bool or character.
For example -
void func(int *arr, int &t)
