Writing Algorithms - Practice

Algorithm Question

A programmer has been asked to write a function which will receive the age of a user and decide if they are old enough to be served a drink (18 or over), returning the result of the decision (yes/no) back to the main program for outputting.

Write a subroutine, in pseudocode, which shows the logic of the problem above.

***There are always different ways to solve a problem. This algorithm is just an example. What is important is that the logic is correct!***

LOGIC:

•Declare a function with a parameter

•If the parameter value is equal or greater than 18 assign variable with string “Yes”

•Else assign variable with string “No”

•Return the value of the variable back to the main program

•Call the function passing an age as an argument, ensuring the function is assigned to a variable which will receive the returned value.

•Output the returned value.

EXAMPLE ALGORITHM:

FUNCTION oldEnough(x):

IF x >= 18:

answer = “Yes”

ELSE:

answer = “No”

RETURN answer

result = oldEnough(age)

OUTPUT result
