15. Pseudocode and built-in subprograms: random function

Activity 14.1

Pseudocode

Pseudocode, or ‘mock’ code, is another way of describing a program. You will need a copy of the pseudocode used in this course (Appendix B of the specification) to answer thesequestions.

•

What does this pseudocode do?

RECEIVE myName FROM (STRING) KEYBOARD

RECEIVE myAge FROM (INTEGER) KEYBOARD

SET AgeInTen TOmyAge + 10

SEND myName “will be” AgeInTen “in 10 years’ time” TO DISPLAY

•

Write the Python code for this program.

Activity 14.2

•

What does this pseudocode do?

SET score TO 119

IF score < 50 THEN SEND “You have lost” TO DISPLAY

ELSE SEND “You have won” TO DISPLAY

END IF

•

Write the Python code for this program.

Activity 14.3

random() function

•

Copy and run this program code:

•

Run the program a few times. What does it do?

•

What is meant by ‘import random’?

•

What happens if you alter the values to 1, 100?

Activity 14.4

Write a program that acts like a dice. After each ‘throw’ of the dice it should ask if the playerwishes to continue and stop when they enter ‘Y’.

Activity 14.5

Write a program that gives the user 10 chances to guess a number between 1 and 10. It then compares their answer with a randomly generated number and stops the program when the number generated matches the number guessed or when the user is out of guesses.
