#include using namespace std; class Rectangle { public: }; int int length; int width; Locate and explain the errors in the following class definitions: Rectangle(int len, int wid) { length = len; width = wid;} void area() { } cout < < length*width < < end1; Rectangle operator++(int) { length++; width++; } Rectangle operator--(int) { length--; width--; } main() { Rectangle r(3, 2); r.area(); r++; r.area(); r--; r1.area(); return 0; Act Go to #include using namespace std; class Rectangle { public: int length; int width; Rectangle(int len, int wid) { length = len; width = wid;} void area() { } } cout < < length width < < endl; Rectangle operator++ (int) { length++; width++; } Rectangle operator--(int) { length; width--; } int main() { double a = 3.2, b = 2.5; Rectangle r(a, b); r.area(); r++; r.area(); r--; r.area(); return 0; Rectangle operator--(int) { length++; width++; } class Rectangle { public: double length; int width; Rectangle(int len, int wid) { length = len; width = wid;
