Let us address the first figure - the rectangle. The others are
similar.  Consider the odometer program that is given as a reference
example in the lab. Specifically, the nested loops code:

 // nested loops
 // printing odometer values for the complete tens of distance
 // ex: for distance of 55, printing from 00 to 49
 for (int i = 0; i < tens; i++)  // outer loop
     for (int j = 0; j < 10; j++)  // inner loop
	 cout << i << j << endl;

Think how, instead of the values "i" and "j", the inner loop prints a
star. Now, the inner loop would then keep track of the stars printed
across the line and the outer loop would move the output to the next
line and keep track of how many lines of stars (or inner loop
invocations) is to be printed.
