- 9. Complete the function prototype so that the callback parameter accepts a closure. The closure accepts a String and an Int parameter but does not return anything. func send(to: String, data: String, callback: _____ ) { // function body }Language : C++ Subject : OOP Suppose we have a class Rectangle which has two data members, length and width. In addition, there should be a static variable, namely allRectanglesTotalArea which stores the area of all the Rectangles created. Furthermore, there should be a function named calcRectangleArea() which calculates the area of rectangle and adds it to the allRectanglesTotalArea. Write a static function nameddisplayAllRectanglesTotalArea()which displays the value of allRectanglesTotalArea. The main function of the program should look like the following. intmain() { Rectangle r1(5.0,4.0); r1.calcRectangleArea(); Rectangle r2(2.5,4.0); r2.calcRectangleArea(); Rectangle::displayAllRectanglesTotalArea(); return 0; }1.
