Create two functions to calculate the area and circumference of the circle using pointer. Area (): this function will accept radius as parameter to calculate area of the circle. Circumference (): This function will accept radius as parameter to calculate circumference. Write a main function that accept radius value from the user. The user may either choose a calculation of area or circumference of circle (use switch statement to handle the choice). The result will be displayed to the user by respective function calling.
