Question

Assign courseStudent's name with Smith, age with 20, and ID with 9999. Use the PrintAll member function and a separate cout statement to output courseStudents's data. End with a newline. Sample output from the given program: Name: Smith, Age: 20, ID: 9999

Answer 1

Answer:

Following are the program in c++

;#include <iostream> // header file

#include <string>

using namespace std;

class student // class

{

   public:

   int ID,age ; // variables

   string courseStudentsname;

   student() // constructor initialize the member

   {

     courseStudentsname="Smith";

     age=20;

     ID=9999;

   }

   void PrintAll() //PrintAll()  function

   {

cout << "Name: " <<courseStudentsname;

cout << ", Age: " << age;

cout << ", ID: " << ID;

}

};

int main() // main function

{

   student e; // create object and call default constructor

   e.PrintAll(); // call the PrintAll() function

   return 0;

}

Explanation:

In the given program we create a three variable inside the class student and declared three variable  ID,age of int type and courseStudentsname of string type after that we create  a constructor and initialize them as value is given in question and finally create a  PrintAll member function which  separate cout statement to output .In the main function create a object class student and call the PrintAll function.

Output:

Name: Smith, Age: 20, ID: 9999

Answer 2

Answer:

Following are the program in the C++ Programming Language:

#include <iostream> //header file

using namespace std; //namespace

class Students //define class

{public: //access modifier

 int id,a ; //set variables

 string courseStudentsname; //set variables

 Students() //set constructor

 {

   courseStudentsname="Smith"; //initialize the value

   a=20;  //initialize the value

   id=9999; //initialize the value

   cout<<endl;

 }

 void PrintAll() //define function

 {

   cout << "Name: " <<courseStudentsname<<endl; //print output

   cout << "Age: " << a<<endl; //print output

   cout << "ID: " << id; //print output

 }

};

int main() //define main function

{

 Students obj; //set object and call constructor

 obj.PrintAll(); // call function through object

 return 0;

}

Output:

Name: smith

Age: 20

ID: 9999

Explanation:

Here, we define class "Students" inside it.

• we define two integer type variable "a" for age of the students and "id" for the id of the students and then we set a string type variable "courseStudentsname" for name of the students.
• we set the constructor in which we assign the value to the variables.
• we set the function 'PrintAll()' in which we print all the variables.

Finally, we define the "main()" Function in which we create the object of the class "obj" and call the the "PrintAll()" through the object of the class.
