Function Templates vs. Auto Keyword

Question

Can the auto keyword in C++11 replace function templates and specializations? If yes, what are the advantages of using template functions and specializations over

Answer 1

The only thing which makes it the auto keyword different from template that is you cannot make a generic class using the auto keyword.

class B { auto a; auto b; }

When you create an object of the above class it will give you an error.

B b; // Give you an error because compiler cannot decide type so it can not be assigned default value to properties

Whereas using template you can make a generic class like this:

template  

class B {
    T a;
};

void main() {
    B b; //No Error
}
