Write an expression that will cause the following code to print "Equal" if the value of sensorReading is "close enough" to targetValue. Otherwise, print "Not equal". Hint: Use epsilon value 0.0001. Ex: If targetValue is 0.3333 and sensorReading is (1.0/3.0), output is:
OBJECT: To compute the net pay of an employee, given his/her pay rate, number of hours, and tax rate.
INPUT: his/her name, pay rate, and number of hours. You will prompt the user with a friendly message to enter the employee’s name, pay rate and number of hours.
Note that you must use the dash (-) to connect the first name to the last name so that the name can be read using the cin statement. For example, John-Doe
OUTPUT: the employee’s gross pay, tax deduction, and net pay. For example:
Name: John-Doe
Your gross pay is: 900.00
Your tax deduction is: 90.00
Your net pay is: 810.00
METHOD: the gross pay is the pay rate times the number of hours.
The tax deduction is computed as follows: If the gross pay is less than 1000.00, it is 10% of the total pay; otherwise, it is 15% of the gross pay.
The net pay is the gross pay minus the tax deduction.

Q1: Write a program that allows a user to enter a string
containing a day of the week ('Sunday', 'Monday', 'Tuesday',
etc.), and uses a switch construct to convert the day to its
corresponding number, where Sunday is considered the first
day of the week, and Saturday is considered the last day of the
week. Print out the resulting day number. Also, be sure to
handle the case of an illegal day name with an otherwise
statement!
