Declare a class/struct named NutritionData that contains these private fields foodName (string) servingSize (int) calFromCarb (double) calFromFat (double) calFromProtein (double) Use the data types in parentheses for the fields. Note that you need to use the proper C++ syntax for the fields. Each field should have a comment documenting what it is for. Place one comment above each field. Add the public default constructor. Read the textbook for the syntax of the default constructor. Write the body of the default constructor inline. The default constructor initializes the fields so that the food name is an empty string and all other fields are 0 for int and 0.0 for double. Add public mutator member functions to set the fields. One mutator member function for each field. Each mutator member function's name should begin with the word 'set' followed by the field name with the first letter changed to uppercase. Each member function should have a comment above the declaration describing its…

PLease! In c++ Important requirements for all questions: • All data members must be declared as “private” • No global variable is allowed to be declared and used • Methods within the class and the requested functions cannot have “cin” or “cout” but it should make use of parameters and return value instead. • “cin” and “cout” should be done in main() or any testing functions • Make sure that you clearly show how the C++ class, its methods and all the functions are being called at least twice and print out its return value and its results properly.

C++ Code: Goal: Write a Class to represent Fractions Write a Fraction class whose objects will represent fractions. For example, a fraction of 3/7 will be represented by a Fraction object whose numerator will be set to 3 and denominator will be set to 7. Implementation Note: For this checkpoint do not reduce fractions (i.e. 15/18 should NOT be reduced to 5/6), do not use "const" (since we haven't discussed in class yet) Attributes: Your class should have exactly two private data members, one to represent the numerator of the Fraction being represented, and one to represent the denominator of the Fraction being represented. (What should be the data type of these member variables?) Member functions: A default constructor that sets the fraction to 0 (what should be the numerator and denominator for such a fraction?). A parametrized constructor takes two integer arguments, a numerator and a denominator, and assigns the attributes accordingly. Arithmetic operations that add,…
