Arrays within a Class

In a C++ program, an Array can be declared as a member of a class. They can be declared as private, public, or protected members of the class. 

For a better understanding of this concept, consider the example below. 

Example:

#include<iostream>

const int size=5;

class student

{

int roll_no;
int marks[size];
public:
void getdata ();
void tot_marks ();
} ;

void student :: getdata ()
{
cout<<"nEnter roll no: ";
Cin>>roll_no;
for(int i=0; i<size; i++)
{
cout<<"Enter marks in subject"<<(i+1)<<": ";
cin>>marks[i] ;
}

void student :: tot_marks() //calculating total marks
{
int total=0;
for(int i=0; i<size; i++)
total+ = marks[i];
cout<<"nnTotal marks "<<total;
}

void main()
student stu;
stu.getdata() ;
stu.tot_marks() ;
getch();
}
