2.setw manipulator

3.setfill manipulator

endl Manipulator:- 

endl is the line feed operator in C++. It acts as a stream manipulator whose purpose is to feed the whole line and then point the cursor to the beginning of the next line. We can use \n (\n is an escape sequence) instead of endl for the same purpose.

setw Manipulator:-

This manipulator sets the minimum field width on output.

syntax:- setw(x)

setfill Manipulator:-

This is used by the setw manipulator. If a value does not entirely fill a field, then the character specified in the setfill argument of the manipulator is used for filling the fields.

#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
int Basic=950, Allowance=95, Total=1045;
cout<<setw(10)<<"Basic"<<setw(10)<<Basic<<endl<<setw(10)<<"Allowance"<<setw(10)
<<Allowance<<endl<<setw(10)<<"Total"<<setw(10)<<Total<<endl;
return 0;
}                                          // must include setw and endl.

INPUT/OUTPUT:-

 Basic              950

 Allowance        95

  Total            1045
