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. This is just a practice question.
In Java, the assignment operator is ______ and the relational operator to determine if two primitive data types are equal is _____

A) Class: A class in C++ is the building block that leads to object-oriented programming. true or false B) Conversion operator: We can also write conversion operators that can be used to convert one type to another type. true or false
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. thanks
C++ Im trying to print the lexeme when the IDENT and INT_LIT tokens are found like the other ones in the picture. Could you try helping me print the IDENT and the INT_LIT found? Im using isalpha for identifiers and isdigit for the integers.
