Subject: Polymorphism Animal eat() grow() Fish eat() Sardine grow() Bass eat() Tiger Figure Mammal Cat eat() grow() Lion eat() Write a complete C++ program (ONE FILE) and create 8 classes that form a class tree as shown in Figure. Every class has only one no-argument constructor, no property. Each class may have an eat() method and/or a grow() method. Both have no return and no parameter. Inside any no-argument constructor, any eat() method or any grow() method, there is only one output statement to print "constructor of xxx class", "eat() method of xxx class", or "grow() method of xxx class", respectively. Here "xxx" represents the current class. Add a line break at the end of the printout. Add another function above, main() with given code below. void display (Animal& al) { al.eat(); al.grow(); } In the main() function, create one object for each leaf classes, i.e. classes Sardine, Bass, Tiger, and Lion. Then call both eat() and grow() from each object. (There is no need to split the code due to the simplicity of all classes. Place all 8 classes, main function, and all other functions in a single source file. i.e upload one .cpp file)

Write a complete C++ program (ONE FILE) and
create 8 classes that form a class tree as shown in
Figure. Every class has only one no-argument
constructor, no property. Each class may have an
eat() method and/or a grow() method. Both have no
return and no parameter. Inside any no-argument
constructor, any eat() method or any grow() method,
there is only one output statement to print
"constructor of xxx class", "eat() method of xxx
class", or "grow() method of xxx class",
respectively. Here "xxx" represents the current class.
Add a line break at the end of the printout.
Add another function above, main() with given code below.
void display (Animal& al) {

In the main() function, create one object for each leaf classes, i.e. classes Sardine, Bass, Tiger, and
Lion. Then call both eat() and grow() from each object.
