Answer to Question #256686 in Algorithms for Dion Martins

Question

Do the necessary planning (IPO) and write an algorithm in pseudo code for the following

The user must enter a positive integer between 5 and 15. If this number is valid, the user must also choose between a triangle (T or t) and a square (S or s). Display suitable error messages if necessary; otherwise, the program must use an asterisk to draw a triangle or a square of the chosen size and display. Use a Select Case structure to make the decision. Display appropriate error messages where applicable.

Answer 1

display 'Enter positive integer x between 5 and 15:'

int x

if $5\le x\le 15$ then

display 'Choose triangle (t) or square (s)'

case t:

draw a triangle using an asterisk

case s:

draw a square using an asterisk

case else:

display 'Error'

else if $x<5$ or $x>15$ then

display 'Error'

end
