From what it looks like, you're being asked to produce 4 programs using those different looping techniques to achieve the same goal - displaying squares of numbers up to 20.

The first step is working out the logic to this, if you can get down on paper in plain English (or pseduocode) exactly what you want to do, then you're halfway there! For example:

number = 1 

Start loop here while number is less than 20 
  print number times number (Square of number) 
Loop back 

Exit

Now all you need to do is apply this using C++, which is pretty easy, let's take this for loop for example:

for (i=1; i<=10; i++) {
  std::cout << "Hello world!\n";
}

We're telling 'i' our number to start at 1 and then continue looping and adding 1 (increment) until we get to 10. This will print "Hello World!" ten times, it doesn't take much more fiddling to get this to multiply our number (i) by itself 20 times, which will be pretty much all you need for the for loop, I'll leave the rest to you

Good luck, buddy!

P.S: This is my first post on D.I.C

And a good post it was. Very nice! Theory and explanatory examples without handing the exact solution.
