Hi, guys i wanted to ask is it really a must to add the keyword class when declaring a function template or can any word be used

Question

template <class T>

Answer 1

A template in general allows the user to use any data type needed by a user for a function.

The best way to achieve this is to use a user-defined data type and change it for the use at compile time...

This can only be achieved if one uses a class, which allows user to define a user-defined data type.

Thus, class is required.

But, we can use typename instead of class, as it helps achieve the same thing...
