VISION is a world leader in manufacturing LCD Televisions. The company has decided that it will allow its

customers to give the dimensions of the TV (in length and width). Once the length and width are ordered the

company will manufacture the TV according to your requirements. In this regard they want you to create a program

that will assist them. Carefully read all the instructions and follow the requirements.  Create a class called vision

 Create three constructors as follows: - A nullary constructor that calls the setlength( ) and setwidth( ) function. - A parameterized constructor that will receive the length and width as integers

- A parameterized constructor that will receive the length and width in float  By using a special function calculate the area of the TV

 Create a function to calculate the price of the TV by multiplying the area with Rs. 65.  Create a display( ) function to show the details of the purchased TV.
