Chapter 15, Problem 15.6E

Write a complete C++ program with the two alternate functions specified below, each of which simply triples the variable count defined in main. Then compare and contrast the two approaches. These two functions are

  1. function tripleByValue that passes a copy of count by value, triples the copy and returns the new value and
  2. function tripleByReference that passes count by reference via a reference parameter and triples the original value of count through its alias (i.e., the reference parameter).

Write a c++ program: Write a function named convertToLowestTerms that inputs two integer parameters by reference named numerator and denominator. The function should treat these variables as a fraction and reduce them to lowest terms. For example, if numerator is 20 and denominator is 60, then the function should change the variables to 1 and 3, respectively. This will require finding the greatest common divisor for the numerator and denominator then dividing both variables by that number. If the denominator is zero, the function should return false, otherwise the function should return true. Write a driver program that uses convertToLowestTerms to reduce and output several fractions.
In C/C++, Function overloading is the process of creating several functions that have exactly the same name. In order to overload successfully, each function must have: A. A different parameter list B. A different number of parameters and a different return type C. An integer on the end of the function name, such as func1()and func2() D. Either A or B E. Both A and C
PLEASE DO IT IN C++   Expand the code program below considering the following specifications: Add a function that will convert from Fahrenheit to Celsius; Add a function showMenu() that will let the user choose between converting from Fahrenheit to Celsius or from Celsius to Fahrenheit; Modify the getinput function so that it accepts a generic input (which can be expressed in either Fahrenheit or Celsius depending on the type of conversion chosen by the user) Modify the  showoutput function so that it displays a generic result (by printing the equivalent temperature of any given temperature input). To sum it all up, there will be five functions in this program: celcius, fahrenheit, showMenu, getinput and showOutput. Please dont do a different code aside from the given code. just modify the given code to get the desired program. Thank you so much!   CODE:  #include <iostream>using namespace std; void showoutput(double fahrenheit);//This function will print the result double…
