Loops
If we want to repeat a set of statements , looping statements are used.
There are two types :
- For ... Next
- Do ....Loop
For ... Next
Probably this is the easiest of the looping statements. The general form is given as
For variable=initial value to final value step value
--------------
-------------
Next variable
1. Display the numbers from 1 to 10.
Dim a as integer
For a=1 to 10
Print a
Next a
Note :
- Step value is used to increment or decrement . In the above program it should have been Step 1, since the difference between two numbers is 1. But Step 1 is the default value so no need to write it.
Dim a as integer
For a=6 to 50 step 2
Print a
Next a
3. Display the following numbers:
100
90
80
....
....
10
Dim a as integer
For a=100 to 10 step -10
Print a
Next a
Note :
Here the numbers are in descending order , therefore step -10.
