This program will obtain the user's information and the radius of a circle.
Then the program should calculate the area and circumference of the circle, 
and display them along with the user's info.

#include <iostream>

  int age; //age of the user
  float gpa; //GPA of user
  char gen; //gender of user
  string firstName; //first name of user
  float rad; //radius that user entered
  float area; //area of the circle
  float circ; //circumference of the circle

  //INPUTS: Ask for the user's info
