### Using Selection and Iteration (loop)

#### Example-1

Write an algorithm for an application that

will display numbers from 1 to 10 and at the same time will display if the number is a multiple of 3.

Use a for loop from 1 to 10 and Inside the body of the for loop:

Check if the number is multiple of 3 (number % 3 = 0) then display the number like this: 6 is a multiple of 3

otherwise just display the number only, for example: 7

##### The algorithm/pseudocode of example-1

#####
for counter=1 , counter <= 10 , counter = counter +1
if counter % 3 = 0
Display counter is multiple of 3
else
Display counter

#### Example-2

Write an algorithm for an application that that will ask the user to enter his salary.

- If the salary textbox is empty the program displays a message asking the user to enter his salary
- Otherwiser, The program reads the salary from the textbox
- The program uses a while loop to calculate the salary for 3 years, each year the employee gets 500 AED increment.
The program displays the year and the salary.

##### The algorithm/pseudocode of example-2

#####
if salary text box is empty
Display an error message
else
Get salary
Set counter to 1
while counter <= 3
Calculate salary as salary + 500
Display counter and salary
counter = counter +1

Here is a scenario of the output:
