C++ Define an "Expression" class that manages expression info: operand1 (integer), operand2 (integer), and the expression operator (char). It must provide at least the following method:- toString() to return a string containing all the expression info such as 50 + 50 = 100 Write a command-driven program named "ListExpressions" that will accept the following commands:add, listall, listbyoperator, listsummary, exit "add" command will read in the expression and save it away in the list "listall" command will display all the expressions "listbyoperator" command will read in the operator and display only expressions with that given operator "listsummary" command will display the total number of expressions, the number of expressions for each operator, the largest and smallest expression values "exit" command will exit the program Requirements:- It must be using the vector object to manage the list of Expression objects. - There should be no global…

PROGRAMMING LANGUAGE: C++ SUBJECT: OOP Task: Suppose you have a class Rectangle with data members width and height. The public member functions of class Rectangle are as follows: setValues(int w, int h); // to set values of width and height of objects of Rectangle class int Area();// to find area of an object of rectangle class biggerRectangle(Rectangle A, Rectangle B); prints the rectangle details which is bigger. Sample Code for passing object to a function is given below: #include <iostream> using namespace std; class CRectangle { int width, height; public: void set_values (int, int); int area () {return (width * height);} void copyData(CRectangle rect); }; void CRectangle::copyData(CRectangle rect) { width=rect.width; height=rect.height; cout<<"width of c = "<<width<<", height of c= "<<height<<endl; } void CRectangle::set_values (int a, int b) { width = a; height = b; } int main () { CRectangle a,b,c;…
