Suppose you work for the HR dept. of a company you wish to write a program to show their earnings per
month Details:
20% of Salary is deducted for tax 5% is deducted for CPP 2% is deducted for EI 8% is deducted for Pension 35.00 is deducted for Health Care Employer pays 85.00 towards Health Care
Write a program that takes in a salary for the month, calculates the deductions, and produces a paystub for the employee
these are matchedby the employer

Formatting Issues# of decimal places arbitrarysome decimals are displayed, others are notnumbers are not aligned
Formatting Output recall that cout has the following syntax:
cout can actually take a formatting manipulator as well:
these manipulators control what the output will look like
cout << expression
cout << expression or manipulator
Fixed and Scientific by default, C++ has a limit on the number of digits it
uses when displaying a floating-point number significant digits on my computer, this default is 6 (common)
what happens when the number has more than 6 digits?
#include <iostream> using namespace std; int main() { cout << 123456.7 << endl; cout << 1234567.8 << endl;
return 0;}
Fixed and Scientific we can instruct C++ to display all of its digits (as
many as it can store) by setting either the fixed flag or the scientific flag
if fixed is used, display numbers in fixed format if scientific is used, display numbers in scientific notation
Syntax:
cout << fixed; // fixed format
cout << scientific; // sci. format
Example:
#include <iostream>#include <iomanip> using namespace std; int main() { cout << 123456.7 << endl;
cout << fixed;
cout << 123456.7 << endl;
cout << scientific; cout << 123456.7 << endl; return 0;}
Fixed and Scientific the statement
cout << fixed
has the effect of turning on fixed mode all floating-point numbers from that point forward
will be displayed in fixed mode until: 1) fixed mode is turned off 2) scientific mode is turned on
the same applies to scientific mode
Example:
#include <iostream>#include <iomanip> using namespace std; int main() { cout << fixed;
cout << 123456.7 << endl; cout << 100.0 << endl;
cout << scientific; cout << 123456.7 << endl; cout << 100.0 << endl;
return 0;}
Fixed and Scientific by default, both fixed and scientific are off
we will refer to this as default mode
to turn off fixed (2 ways) cout << resetiosflags(ios::fixed); cout.unsetf(ios::fixed); // textbook way
to turn off scientific: cout << resetiosflags(ios::scientific); cout.unsetf(ios::scientific); // textbook way
Example:
#include <iostream>#include <iomanip> using namespace std; int main() { cout << fixed;
cout << 123456.7 << endl; cout << 100.0 << endl;
cout << resetiosflags(ios::fixed);
cout << 123456.7 << endl; cout << 100.0 << endl;
return 0;}
setprecision by default, C++ has a limit on the number of digits it
uses when displaying a floating-point number significant digits on my computer, this default is 6 (common)
can this number be set higher, without resorting to fixed or scientific mode?
use the setprecision flag
Syntax:cout << setprecision( ); # of digits
Example:
#include <iostream>#include <iomanip> using namespace std; int main() {
cout << 123456.7 << endl;
cout << setprecision(7);
cout << 123456.7 << endl; return 0;
}
setprecision in default mode, setprecision sets the
number of digits for displaying what does it do in fixed and scientific mode?
sets the number of decimal places
Example:#include <iostream>#include <iomanip> using namespace std; int main() {
cout << setprecision(3);
cout << 123.45 << endl;
cout << fixed;
cout << 123.45 << endl;
cout << scientific;
cout << 123.45 << endl; return 0;
}
setprecisionnote that setprecision does not change
the value being stored in memory it simply affects the displayed value
Example:#include <iostream>#include <iomanip> using namespace std; int main() {
double x = 141.5;
cout << setprecision(4); cout << x << endl;
cout << setprecision(3); cout << x << endl;
cout << setprecision(4); cout << x << endl; return 0;
}
showpointby default, the number 123.0 is shown as
123 in default mode for some compilers, this is also the case in fixed
modeuse the showpoint flag to force floating point
numbers to show their decimal place
Example:#include <iostream>#include <iomanip> using namespace std; int main() {
cout << 123.0 << endl;
cout << showpoint; cout << 123.0 << endl; return 0;
}
Back to our example:suppose I want all of my numbers to be
displayed with exactly two decimal placesuse the following formatting flags:
fixed showpoint setprecision(2)

Nice Output:
but what happens if the salary is much bigger (or smaller)
Earnings Deductions
Description Amount Description Employee Employer
Salary 3000 Tax 600
CPP 150 150
EI 60 60
Pension 240 240

Total 3000 Total 1085 535
Net Pay 1915
Our spacing worked when:salary was a four digit numberEI was a three digit number
It would be nice if:everything in each column was printed at
the same width, regardless of how many characters the actual value has
setwstands for set widthsets the number of characters that will be
used to display the next expressionsyntax:
cout << setw( ); # of chars
Example:#include <iostream>#include <iomanip> using namespace std; int main() {
cout << "|" << "Kev" << "|" << endl; cout << "|" << setw(5) << "Kev" << "|" << endl; return 0;
}
Kev|
What happened? cout << "|" << setw(5) << "Kev" << "|" << endl;
| |
This tells C++ to use 5 characters to output the nextexpression.
Kev|
What happened? cout << "|" << setw(5) << "Kev" << "|" << endl;
| |
This expression requires only three characters for output.
Kev|
What happened? cout << "|" << setw(5) << "Kev" << "|" << endl;
| |
This expression requires only three characters for output.• when the field width is bigger than the expression, C++ "pads" the expression with spaces• the padding is placed on the left hand side
• expression is padded with two spaces before output• the expression now has 5 characters
setwwhat happens if the output requires more
characters than setw gives it?
cout << setw(5) << "Computer Science" << endl;
• the field width is always set at least as big as the output
Noteunlike setprecision, fixed, scientific, and
showpoint, setw only applies to the next expression (not all expressions hereafter)
cout << setw(5) << "Kev" << "Kev" << endl;
displayed with 5 characters (2 pad spaces)
displayed with 3 characters (no padding)
Back to our previous example: we can break up the table into 6 columns each column has a specific width

When outputting our data, we will include a setw for each expression, depending on which column it is in for the first column:
cout << setw(14) << "Salary" for the second column:
cout << setw(8) << salary; etc
What do we do with a blank field entry? cout << setw(5) << ""; // output 5 blank spaces
Write a program that takes in a salary for the month, calculates the deductions, and produces a paystub for the employee cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Earnings" << setw(8) << "" << setw(5) << "" << setw(14) << "Deductions" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Description" << setw(8) << "Amount" << setw(5) << "" << setw(14) << "Description" << setw(10) << "Employee" << setw(10) << "Employer" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Salary" << setw(8) << salary << setw(5) << "" << setw(14) << "Tax" << setw(10) << tax << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "CPP" << setw(10) << cpp << setw(10) << cpp << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "EI" << setw(10) << ei << setw(10) << ei << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "Pension" << setw(10) << pension << setw(10) << pension << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "Health Plan" << setw(10) << 35.00 << setw(10) << 85.00 << endl;

one long blank instead of:
cout << setw(14) << "" << setw(8) << "";
we could write: cout << setw(22) << "";
