2 | P a g e

• Execute the program

• Save with .cpp extension

• Compile the program for errors

• Filename. Class will be created (if no errors)

• Run the .class file

5. Write the C++ program to read and print the data using arrays?

Answer:

//Program using arrays

#include<iostream>

#include<conio.h>

using namespace std;

int main()

{

int i,a[10];

cout<<"Enter the value of n";

cin>>n;

cout<<endl<<"Enter the values";

for(i=0;i<n;i++)

{

cin>>a[i];

}

cout<<endl<<"The elements are ";

for(i=0;i<n;i++)

{

cout<<endl<<a[i];

}

6. State the following statements true or false

a. If no function used in program then default function is main ( ) [ True]

b. cout and cin functions are supported by #include<conio.h> [False]

c. Templates used in C programming language [False]

7. Discriminate between function overloading and function overriding?

Answer: Function overloading is an example of static polymorphism. In this same function

name is used for different functions but parameters are different. Function overriding is an

example of dynamic polymorphism. In this same function name is used for different

functions even the parameters are also same.

8. Label the below instructions for the given below program?

{ student s1 // s1 object created for class student

s1.getdata ( ); //s1 invoke with member functions getdata()

s2.printdata( ); //s1 invoke with member functions printdata()

getch(); return 0;}
