8.12 PROJECT 9—IMPROVING YOUR MULTIPLICATION SKILLS

8.12.1 Description
This program helps the young learners to improve their multiplication skills. The program
displays the multiplication of two integer numbers without the result. The numbers are cho-
sen randomly between 1 and 100. The user is given 20s to calculate the result. After this time,
the result is displayed on the screen so that the user can check with his/her own result. The
process is repeated after 5s.

8.12.2 Aim

The aim of this project is to show how the various serial communication functions and con-
trol codes can be used in a program.

8.12.3 The PDL

The PDL of the program is shown in Fig. 8.34.
