Q.1) Write a C++ program to create a
class Student which contains data members as Roll_Number, Stud_Name,
Percentage. Write member functions to
accept Student information. Display all
details of student along with a class obtained depending on percentage. (Use array of objects)
#include<stdio.h>
#include<conio.h>
#include<iostream.h>
class
student
{
char
name[10];
float
per;
int
rno;
public:
void
accept()
{
cout<<"\nEnter
rno : ";
cin>>rno;
cout<<"\nEnter
name : ";
cin>>name;
cout<<"\nEnter
percentage : ";
cin>>per;
}
void
display()
{
cout<<"\nrno
= "<<rno;
cout<<"\nName
= "<<name;
cout<<"\nPercantage
= "<<per<<"%";
if(per>=70&&per<=100)
cout<<"\nDistinction";
else
if(per<70&&per>=60)
cout<<"\n1st
class";
else
if(per<60&&per>=50)
cout<<"\n2nd
class";
else
if(per<50&&per>40)
cout<<"\npass
class";
else
cout<<"\nfail";
cout<<"\n=================================";
}
};
void
main()
{
int
n,i;
student
ob[10];
clrscr();
cout<<"enter
no of students";
cin>>n;
for(i=0;i<n;i++)
{
ob[i].accept();
}
for(i=0;i<n;i++)
{
ob[i].display();
}
getch();

Q.2) Create a class Distance which
contains data members as: kilometer, meter. Write C++ program to perform
following functions:
i.
To accept a distance
ii.
To display a distance
iii.
To overload += operator to add two distances.
iv.
To overload > operator to compare two distances
#include<iostream.h>
#include<conio.h>

cout<<"\naddition of two distances
