HIGH LEVEL LANGUAGE PROGRAMMING – BASIC CONSTRUCTS
For example, to produce:
random numbers between 1 and 20, change it to
number = Int (Rnd * 20) + 1
random numbers between 51 and 60, change it to
number = Int (Rnd * 10) + 51
random even numbers between 0 and 10, change it to
number = 2 * Int (Rnd * 6)
Try experimenting with this line until you understand how
it works. Sometimes it takes a little thought to work out
exactly what numbers to put in, so that you get the right
range and don’t miss out the highest or lowest number.
Test your program with the following lines of code.
In each case, make a note of the results, and explain what you get.
line of code
number = Int(Rnd * 200) + 1
results
explanation
number = Int(Rnd * 20) + 1
number = Int(Rnd * 100) + 2000
number = 2 * (Int(Rnd * 50) + 1)
number = 2 ˆ (Int(Rnd * 8) + 1)
Tasks:
• Modify your program so that when you click on the
button, it produces a single dice roll (a random
number between 1 and 6). Hint: you won’t need a
For ... Next loop.
• Modify your program so that it produces a double
dice roll, and displays the number on each dice and the total score.
Hint: you will need to generate two random numbers every time you
click the button.
