OOP Lab 18: Fraction Class Arithmetic, Relational & Unary Operators

LIVE← Prev Next →

Problem Objective

Create a Fraction class to perform arithmetic and relational operations on rational numbers in reduced form:

Data Members & Reduction:

◦
Private attributes: int numerator, int denominator.
◦
Helper function reduce() using Greatest Common Divisor (gcd) ensuring denominator is positive and fraction is in irreducible form.
◦
Constructor Fraction(int num = 0, int den = 1).

Overloaded Operators:

◦
Arithmetic Operators: +, -, *, /
◦
Relational / Comparison Operators: ==, !=, <, >, <=, >=
◦
Unary Minus: Fraction operator-() const returning negative fraction.
◦
Increment & Decrement:
◦
Pre-increment ++f and Post-increment f++
◦
Pre-decrement --f and Post-decrement f--
◦
Compound Assignment: +=, -=, *=, /=

Display Method:

◦
display() const: Prints fraction in a/b format.

In `main()`:

◦
Create fractions (e.g. f1 = 1/2, f2 = 3/4).
◦
Test arithmetic, relational comparisons, unary negation, pre/post increments, and compound assignments.

Expected Terminal OutputStandard Out

f1 = 1/2, f2 = 3/4
f1 + f2 = 5/4
f1 - f2 = -1/4
f1 * f2 = 3/8
f1 / f2 = 2/3
Unary -f1 = -1/2
f1 < f2: TRUE
f1 == f2: FALSE
Pre-increment ++f1 = 3/2
f1 += f2 -> 9/4

[✓] Fraction operator overloading verified (Time: 0.008s, Memory: 2.1 MB)

Execution Constraints

›Denominator must never be zero
›Fractions must always be stored in lowest reduced form
›Support pre and post increment/decrement syntax (int parameter for post)
