A Fraction denominator must not ever become 0. You can enforce this invariant through:

class Fraction {
. . .
public:
Fraction(int, int);
Fraction get() const;
Fraction set(int, int);
};


a) the implementation of the accessor member
b) the selection of data members
c) the implementation of the mutator member
d) by using the access modifier private in place of public
e) the implementation of a destructor

Answer 1

A fraction denominator must not ever become zero. This invariant can be enforced through the implementation of the mutator member. Here are a few more details about how to enforce this invariant through the implementation of the mutator member.

In C++, the mutator method is used to modify the value of an object's data members. If a mutator member is not properly implemented, it can lead to problems like the denominator of a fraction becoming zero. In order to avoid this problem, the mutator method must be implemented with care. It should include checks to ensure that the denominator of a fraction never becomes zero.

Here is an example of how the mutator member can be implemented in the given code As you can see, the implementation of the mutator member includes a check to ensure that the denominator of a fraction is not zero. If the denominator is zero, an exception can be raised or the error can be handled in some other way. Otherwise, the numerator and denominator of the fraction are updated as per the user input.

There are 20 amino acids that are uniquely combined to make up proteins important for human health and wellness. These 20 amino acids differ from one another based on their side chains, which are also known as R groups.

Amino acids are the building blocks of proteins. In order for a protein to form, amino acids must be linked together in a specific order and shape. This is known as the protein’s primary structure. The side chains of the amino acids play a crucial role in determining the protein’s overall shape, which in turn influences its function.There are two types of amino acids: essential amino acids and non-essential amino acids. Essential amino acids are those that cannot be produced by the body and must be obtained through the diet.

Non-essential amino acids, on the other hand, can be produced by the body.Both essential and non-essential amino acids are necessary for human health and wellness. They play important roles in a wide range of bodily processes, from muscle growth and repair to the production of hormones and enzymes.
