2. TASK
• A given organisation has 30 employees with a policy of no increase
nor decrease in the number of staff. You are required to design a
computer program that computes the net pay of employees. Note
that the system requires the following
• Identification number of employees
• Name of employees
• Sex
• Department
• Gross pay
• Birth day of employees
• Etc
• Note tax = 30% of the gross pay

3. REQUIRED
• A company requires a data base of its employees
with all the details of the employees including the
gross pay
• A computer program that computes the net pay of
employees putting into consideration the gross
pay and the tax rate of employees
• Note, in Uganda employees earning bellow
shs.130000 do not pay tax, in our program we
considered employees earning a gross pay bellow
shs.200000 do not pay tax

4. CHOICES AND DECISIONS
• We decided to use c programming language
when designing the program that computes the
net pay because of the following
1. C language is simple to learn and adopt to.
2. C language is portable, a program can be
designed on one system and be used on a
different system

5. STEPS IN DESIGNING THE PROGRAM
• After designing a database system of the 30
employees, we were in position to design the
program
• We calculated the tax paid by each employee
putting into consideration the gross pay earned
i.e. gross pay > 200000
Tax paid= 0.3 * gross pay
While gross pay < = 200000
Tax paid = shs.0

6. CONTINUATION
• After calculating the tax paid by each
employee,
We calculate the net pay of the employees
i.e. net pay = gross pay – tax paid
• from the above employees earning
shs.200000 and below do not pay tax and there
fore their
Net pay = gross pay

7. C TECHIQUES USED
• In the program we used a “for” loop to control the
number of employees to which the net pay is
calculated.
• All the details of the employee as got from a database
of the company are entered in the main function under
the “for” loop, like the name , sex and gross pay
• Our for loop statement has three parts, the part that
initialises the employee, its executed, then the second
condition if its true, the loop continues i.e. if the
number of employees is still less than 30, when the
second condition is wrong, the program exits the loop.

8. CONTINUATION OF THE TECHIQUES
• The “for” loop statement is nested as it
contains the “if” statement in it.
• The use of the “if ” statement is to control the
calculation of net pay, as it contains a Boolean
statement i.e. gross>200000 where if the
conditions is true, the calculation of the net
pay is executed but when the condition is false
the calculation are not executed as shown
above.

9. PROGRAM CYCLE
• Including a header statement.
• Initialising the size of employees to be considered
• Declaring local variables to be used in the
program
• Introducing the main function, and in the main
function we declared a “for” loop and an if
condition in it
• Entering the employee data form the data base i.e.
name, sex, department, gross pay.

10. • At the if condition we check whether the gross
pay is greater than 200000 and if yes tax is
calculated and net pay got by subtracting the tax
paid from gross pay
When the gross pay is less than 200000 or equal to
200000, the tax paid is zero(0) and thus the net
pay equals to the gross pay
At the end the program prints the name
department and gross pay plus net pay in tabulat
form.

15. CONCLUSION
• From above the program calculates the net pay
of the employees putting into consideration the
gross pay,
• The program is case sensitive on the amount
earned by each employees as those earning
shs.200000 and below
