Expert Solution & Answer
Chapter 18.2, Problem 18.8CP
Explanation of Solution
Requirement of type parameter:
“No”, the type parameter is not required to be a single letter written in upper case.
Explanation:
- In general, the type parameter is a single letter written in upper case.
- Type parameter holds the value of specific type that a user specifies when they create an instance of generic type.
- Type parameter names which are commonly used are,
- “T”-It is used for representing general type.
- “K”- It is used for representing a type of key in a class which consists of key-value pairs...

printSmaller is a function that accepts two int parameters and returns no value. It will print the value of the smaller one parameters. The function protoype is as follows:
void printSmaller(int num1, int num2);
write the statments to read two integers and call this function to display the smaller one.
Please answer in C++ / Text book question / C++ for scientist and Engineers 3rd edition
Construct a class named Fractions containing two integer data members named num and denom, used to store the numerator and denominator of a fraction having the form num/denom. Your class should include a default constructor that initializes num and denom to 1 and four operator functions for adding, subtracting, multiplying, and dividing the two fractions, as follows:
Addition: a/b + c/d = (a * d + b * c) / (b * d)Subtraction: a/b - c/d = (a * d - b * c) / (b * d)Multiplication: a/b * c/d = (a* c) / (b * d)Division: (a/b) / (c/d) = (a * d) / (b * c)
Finally, your class should have a member function that reduces each fraction to its terms (refer to Exercise 15 in Programming Projects for Chapter 6 for how to do this) as well as input and output functions for entering and displaying a fraction.

- C++arrow_forwardC++ Create a class Rectangle. The class has attributes length and width, each of which defaults to 1. It has member functions that calculate the perimeter and the area of the rectangle. It has setter and getter functions for both length and width. The program should ASK THE USER TO INPUT length and width value. The set functions should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. A sample output of your program should look like follows: length = 1.0; width = 1.0; perimeter = 4.0; area = 1.0 another example: length = 5.0; width = 4.0; perimeter = 18.0; area = 20.0 There should be three files and ONE class only. .h file contains class definition, .cpp file contains the implementation of the class in .h file and main.cpp should contain the driver code.arrow_forwardYOu WIll Lose Data Divisibility Test A number x is said to be divisible by a number y if when x is divided by y (x%y) the remainder is zero.
