8. Rewrite the WIDTH program so that the characters on each line between the location name and the population number are filled in with periods instead of spaces.

Chapter 2: 

C++ Programming Basics 

Programming Exercise

Problem # 8:

When a value is smaller than a field specified with setw(), the unused locations are, by default, filled in with spaces. The manipulator setfill() takes a single character as an argument and causes this character to be substituted for spaces in the empty parts of a field. Rewrite the WIDTH program so that the characters on each line between the location name and the population number are filled in with periods instead of spaces, as in

Portcity.....2425785

Solution:

#include <iostream>
#include <iomanip>     // for setw
#include <conio.h>
using namespace std;
int main()
{
    long pop1=2425785, pop2=47, pop3=9761;
    cout<<setfill('.')<<setw(8)<<"LOCATION"<<setw(12)<<"POPULATION"<<endl
    << setw(8) << "Portcity" << setw(12) << pop1 << endl
    << setw(8) << "Hightown" << setw(12) << pop2 << endl
    << setw(8) << "Lowville" << setw(12) << pop3 << endl;

    return 0;
}
