 * Name:Wang Chaoran
 * Description:Write a program that generates two integers under 100
 * and prompts the user to enter the addition of these two integers.
 * The program then reports true if the answer is correct, false otherwise.
 * The program is similar to Listing 3.3. Include appropriate comments in your
 * program.
