Explanation of Solution

Class template:

In C++, a class template is used to create a common version of a class and it does not have any additional code for handling multiple data types.

Defining class template objects:

Definition of class template object is little different from normal class object definition.

  • The difference is, to specify the data type that user want to pass as the type parameter.
  • This data type should be placed inside a pair of an angle brackets, which is followed by the class name is as follows:

  Class_name<int> object_name;

From the above declaration, “int” is a data type for the type parameter of the given class.

Example:

For example, consider the following program which is used to square the given value of any types, in which the class template “List” has been defined and its object has been defined in main() function:

//include the required header files

#include <iostream>

using namespace std;

//class template

template<class T>

//definition of the template class

class List

{

    //declare the class data member

    T x;

    //access specifier for the class member functions

    public:

    //default constructor

    List()

    {

        x=0;

    }

    //this member function is used to get the user input

    void getvalues()

    {

        //get the value from the user

member and non-member functions c++
TRUE OR FALSE: In C++, comments that begin with the "multi-line" comment symbol can't be nested.   A member function of a class has access to only the public data members of the class.   If a C++ function does not take any parameters, parenthesis around the empty parameter list are still required.   The size of a pointer variable depends on the type that it is pointing to.
Suppose your program uses a class template named List, which is defined as template<class T> class List{// Members are declared here… }; Give an example of how you would use int as the data type in the declaration of a List object. (Assume the class has a default constructor.)
