I have an array with the following elements:

array[0] = "car"
array[1] = "bike"
array[2] = "motorcicle"
.......
array[n] = .........

And I have a string with the following text.

"Today I went to school by car. I saw............ "

What I am trying to do is that everytime the program finds one of the words
from the list in the text,
it will place an astherisc * to replace that word.

But I cannot figure out how to do this because it is an array not a regular
expression.
