Write a rational number class. Recall a rational number is a rational number, composed of two integers with division indicated. The division is not carried out, it is only indicated, as in 1/2, 2/3, 15/32. You should represent rational numbers using two int values, numerator and denominator. A principle of abstract data type construction is that constructors must be present to create objects with any legal values. You should provide the following a default constructor to initialize the data members: 1. A default constructor to make rational objects without any argument. The constructor sets the rational object's numerator to 0, and denominator to 1. 2. EXTRA CREDIT: implement two other constructors: one that takes just numerator and one that takes both as parameters. REMEMBER that fractions cannot have a denominator of 0. You should also provide the following member functions (no simplifying rationals until part2): 1. an input function that reads from standard input the value for current object. The input should be in the form of 2/3 or 27/51. 2. an output function that displays the current object in the terminal. The output should also be in the form of 2/3, i.e., numerator/denominator. 3. Two accessor (getter) functions that return the numerator and denominator respectively. 4. a Add function that takes two rational objects as parameters. It sets the invoking object to be the sum of the two given rational numbers like op1 + op2. 5. a Subtract function, which will set the invoking object to the difference of op1 - op2 6. a Multiply function, which will set the invoking object to the product of op1 * op2 7. a Divide function, which will set the invoking object to the quotient of op1 / op2.

Write a rational number class. Recall a rational number is a rational number, composed of two integers
with division indicated. The division is not carried out, it is only indicated, as in 1/2, 2/3, 15/32. You
should represent rational numbers using two int values, numerator and denominator.
A principle of abstract data type construction is that constructors must be present to create objects with
any legal values. You should provide the following a default constructor to initialize the data members:
1. A default constructor to make rational objects without any argument. The constructor sets the
rational object's numerator to 0, and denominator to 1.
EXTRA CREDIT: implement two other constructors: one that takes just numerator and one that
takes both as parameters. REMEMBER that fractions cannot have a denominator of 0.

You should also provide the following member functions (no simplifying rationals until part2):
1. an input function that reads from standard input the value for current object. The input should be in
the form of 2/3 or 27/51.
2. an output function that displays the current object in the terminal. The output should also be in the
form of 2/3, i.e., numerator/denominator.
Two accessor (getter) functions that return the numerator and denominator respectively.
4. a Add function that takes two rational objects as parameters. It sets the invoking object to be the
sum of the two given rational numbers like op1 + op2.
a Subtract function, which will set the invoking object to the difference of op1 - op2
a Multiply function, which will set the invoking object to the product of op1 * op2
7. a Divide function, which will set the invoking object to the quotient of op1 / op2.

Note the formula for adding two rational numbers (same for subtraction but change + to -):
numerator1/denominator1
+ numerator2/denominator2 =
( n1*d2 + n2*d1)/ (d1* d2)
Set the numerator to the top part ( nl * d2 + n2 * d1) and the denominator to the bottom (d1 * d2) in your
object. Remember that division multiplies the reciprocal of the second operand.
Main Program
The following code segment demonstrate the usage of the above mentioned member functions, and
constructors. Your main function should be some code like this.
int main ()

constructor

cout << "Enter opl (in the format of p/q) : ";
// TODO: use your input member function to read the first op1

// Main loop to read in rationals and compute the sum
do {
cout << "\nEnter operator [+, -,
1, *, =, c (lear),

// TODO: read in a character operator into oper as shown above.
// TODO: Pseudocode below says when to use your input member
function to read the second operand (i.e. rational object)

// 'a' to test accessors, ' q' to quit.
} while (oper != 'q');
