Answer to Question #213766 in C++ for Hemambar

Question

Create two classes IntArray to store the set of integer numbers and FloatArray to store decimal

numbers. Add a member function read() for both classes for reading inputs. Create two objects ‘x’

for IntArray and ‘y’ for FloatArray. Read the inputs for x and y. Using a friend function maxmin(x,y),

display the maximum and minimum among the set of integers and decimal numbers.
