INFORMATION
SYSTEMS IS 115: INTRODUCTION TO PROGRAMMING
IS 115 is
Introduction to Programming. It is the first course in learning how to write
computer programs. IS 115 uses the RAPTOR and Python programming languages to
teach programming. RAPTOR is a graphical flowchart programming environment.
Python is a text-based programming language.
Here’s a practice
exam or homework for INFORMATION SYSTEMS IS 115: INTRODUCTION TO PROGRAMMING.
Write a program
in ANY programming language that fulfills the following requirements (solution
is shown in Raptor):
Requirement 1: Do
not use loop. Ask user to enter the numerators and denominators of 2 fractions.
Requirement 2: Do
not use loop. If user enters a number other than 2, 3, 5, and 7, end program
abruptly, otherwise output the product and the quotient of the first and second
fractions.
Requirement 3: Do
not use loop. Do not reduce the resulting fractions. Show and have your program
tested by the tutor.
EXAMPLE: THIS IS
ONLY AN EXAMPLE:
Enter numerator
n1: #
Enter denominator
d1: #
Enter numerator
n2: #
Enter denominator
d2: #
n1/d1 * n2/d2 =
#/# and n1/d1 / n2/d2 = #/#
Extra and
optional program (no solution shown): Reduce the resulting fractions WITHOUT
USING A LOOP.
Go with the flow.
