Question

Define a class Candidate in C++ with the following specification :

Private Members :

A data members Rno(Registration Number) type long

A data member Cname of type string

A data members Agg_marks (Aggregate Marks) of type float

A data members Grade of type char

A member function setGrade () to find the grade as per the aggregate marks obtained by the student. Equivalent aggregate marks range and the respective grade as shown below.

| Aggregate Marks | Grade |
| >=80 | A |
| Less than 80 and >=65 | B |
| Less than 65 and >=50 | C |
| Less than 50 | D |

Public members:

A constructor to assign default values to data members:

Rno=0,Cname=”N.A”,Agg_marks=0.0

A function Getdata () to allow users to enter values for Rno. Cname, Agg_marks and call function setGrade () to find the grade.

A function dispResult( ) to allow user to view the content of all the data members.

Answer 1

class Candidate

{ long Rno;

char Cname[20];

float Agg_marks;

char Grade;

void setGrade()

{ if (Agg_marks>= 80)

Grade = ‘A’;

else if(Agg_marks<80 && Agg_marks>=65)

Grade = ‘B’;

else if (Agg_marks<65 && Agg_marks>=50)

Grade =’C’;

else

Grade=’D’;

}

public:

Candidate()

{

Rno=0;

Strcpy(Cname,”N.A.”);

Agg_marks=0.0;

}

void Getdata ()

{

cout<<”Registration No”;

cin>>Rno;

cout<<”Name”;

cin>>Cname;

cout<<Aggregate Marks”;

cin>>Agg_marks;

setGrade();

}

void dispResult()

{

cout<<”Registration No”<<Rno;

cout<<”Name”<<Cname;

cout<<Aggregate Marks”<<Agg_marks;

}
