Concept explainers

Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Subject name is C++ Write a program to overload binary - (minus) operator for Number class using friend function. Number class have two data members as num1 and num2.
Illustrate using suitable example, why friend function in needed for operator overloading when you can achieve the same using member function.
This is in c++. Create a class of function objects called StartsWith that satisfies the following specification: when initialized with character c, an object of this class behaves as a unary predicate that determines if its string argument starts with c. For example, StartsWith(’a’) is a function object that can be used as a unary predicate to determine if a string starts with an a. So, StartsWith(’a’)("alice") would return true but StartsWith(’a’)("bob") would return false. The function objects should return false when called on an empty string. Test your function objects by using one of them together with the STL algorithm count_if to count the number of strings that start with some letter in some vector of strings. So basically, I want a class that returns true or false based on if the name that is typed starts with the character that I put down.
3. Which one is incorrect in case of Operator overloading? A. The syntax of overloaded operator cannot be overridden. They follow syntax rules of original operators B. We can give new meaning to an operator C. Number of operands, precedence and associativity remains same D. We cannot use friend function to overload certain operators =,0,[],->.
