C++ please.

Write a program that takes in input the side of a square or radius of a circle followed by the desired option 1 (for square) ,2 (for cirale) Enter these values in the input box. The program will output the final area Formula for computing area: 1. square-> side side 2 circle >3.14*radius radius Sample input: So, for example you enter the following input in the input box in the input box 3 2 The first input 3 can be either the radius of the circle or side of a square. But the second input 2 implies we have to compute the area of the circle. So, the code should print the area of the circle considering 3 as radius of the circle Sample output for the above input: 28.26 If any other value for option is given (other than 1 or 2) the output should be: Wrong option Check for the correctness of the side or radius (must be greater than 0), If its not correct, the output message should contain the word error
