Display one value during each iteration

During each iteration of the inner loop, the first boldface statement in Listing 2 computes and displays a single numeric value followed by a space as shown in Figure 1.

(If you were to run the program on an incredibly slow computer, you would see the values in Figure 1 being displayed one after the other moving from left to right across the screen during one set of iterations of the inner loop.)

This process continues until the conditional clause causes the inner loop to terminate, producing one row of output values as shown in Figure 1.
