In essence, this is what is known as generic programming; this term is a useful way to think about templates because it helps remind the programmer that a templated class does not depend on the datatype (or types) it deals with. To a large degree, a templated class is more focused on...
C++ code snippet to declare and use of a template, Template Declaration and Use in C++ programming language.
The idea of template specialization is to override the default template implementation to handle a particular type in a different way. For instance, while most vectors might be implemented as arrays of the given type, you might decide to save some memory and implement vectors of bools as a ...
In the above example we defined a class template Stack. In the driver program we instantiated a Stack of float (FloatStack) and a Stack of int(IntStack). Once the template classes are instantiated you can instantiate objects of that type (for example, fs and is.) A good programming pract...
Set in C++ STLThe Standard Template Library (STL) is a set of C++ template classes to provide common programming data structures and functions such as lists, stacks, arrays, sets etc. Therefore, Set can be implemented with help of STL too....

Lvalue reference is a reference which binds to a lvalue. This is very similar to how we used to refer to a variable in traditional C++ or C language, i.e. by using ampersand symbol (&) with the variable itself to refer to its address....
