A

company

requests

a

program

to

calculate

and display

their

workers'

weekly salary with consideration of overtime. Overtime need

to

be

considered

when

a

worker

worked

more

than

40

hours

per

week. Meanwhile,

the salary

is

based on

how many

hours

a worker

worked multiply

with the hourly rate.

The

first

40

hours

pay

rate

is

RM5.00.The

pay

rate

after

the

first

40 hours is

RMs.50.

The

maximum

working

hours

is only

60

hours.

when

the working

hours is more

than

60

hours,

the

program

will

display appropriate message

and

will not calculate

the weekly

salary.
