The for loop is simply a while loop with a bit more code added to it. The common tasks that are covered by a for loop are:
The for loop allows you to define these steps in one easy line of code. It may seem to have a strange form, so pay close attention to the syntax used!
Let us take the example from the while loop lesson and see how it could be done in a for loop. The basic structure of the for loop is as follows:
Notice how all
the steps of the loop are taken care of in the for loop
Each step is separated by a semicolon: initiliaze counter, conditional statement, and the counter increment.
A semicolon is needed because these are separate expressions.
However, notice that a semicolon is not needed after the "increment counter" expression.
Here is the example of the brush prices done with a for loop .
