Question No: 29 ( M a r k s: 2 )
What is difference between endl and \n?
Endl is manipulator and it insert new line character and flush the stream.
\n is control charcter which is used to insert linebreak
Question No: 30 ( M a r k s: 2 )
What does code optimization mean?
It is process by which we make over code such a way that it improves the speed of program. By use of optimization we refine program codes in such a way that it run faster and consume less memory. We do it in such a way that output quality is not compromised

Question No: 36 ( M a r k s: 5 )
Write a program which defines five variables which store the salaries of five employees, using setw and setfill manipulators to display all these salaries in a column.
Note: Display all data with in a particular width and the empty space should be filled with character x
Output should be displayed as given below:
xxxxxx1000
xxxxxx1500
xxxxx20000
xxxxx30000
xxxxx60000
Answer:
#include <iostream.h>
#include <iomanip.h>
main(){
int sal1 =1000;
int sal2 =1500;
int sal3 =20000;
int sal4 =30000;
int sal5 =60000;
cout << setfill ('x') << setw (10);
cout<< sal1<<endl;
cout << setfill ('x') << setw (10);
cout<< sal2<<endl;
cout << setfill ('x') << setw (10);
cout<< sal3<<endl;
cout << setfill ('x') << setw (10);
cout<< sal4<<endl;
cout << setfill ('x') << setw (10);
cout<< sal5<<endl;
int i=0;
cin>>i; // to stop the screen to show the output
}
