Write a c++ porgram containing a class called operator demo with one integer type data member. implement the default constructor, and the constructor with one int parameter. overload the * and + operators to multiply and add the data members of two instances of the class operator demo. also, overload the operator to allow subtraction of the data members of two instances of the class operator demo! write a program to test all the member functions and overloaded operators in your class definition.

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
