			...
			Body of loop

			}
			   
E.g.

		for( int i=0; i < 10; i++)
			{
			cout << "I is: " << i << endl;
			}

Exercise: Write a program that computes PI using the first 100 terms of the following sequence:

             PI = (4/1) - (4/3) + (4/5) - (4/7) + (4/9) - (4/11) + ...

Use a for loop to implement the above sequence, then use a while loop to implement the above sequence.
