从键盘输入两个小于100的整数A和B，计算A与B两数的基本算数运算。需要注意的是：A和B的每一位数位上的数字由对应的英文单词给出。
系统要求：
（1）系统由菜单做导航，给出输入数据功能、退出程序功能、数据输入功能并能够循环输入执行运算等。
（2）在数据运算输入功能菜单下分别给出A与B的相加运算、A与B的相乘运算、A与B的相减运算、A与B的相除运算、A与B的相除取于运算等功能。
（3）当A输入为zero，同时B输入为zero时自动返回菜单上一级。(From the keyboard input two less than 100 integers A and B, A and B calculated the basic arithmetic operations. It should be noted that each digit in A and B is given by the corresponding English word.
System requirements:
(1) the system is guided by the menu, which gives input data function, exit program function, data input function, and can cycle input and execute operations.
(2) in the data input function menu are A and B, A and B addition multiplication, A and B, A and B subtraction operation, A and B division division to operation and so on.
(3) when the A input is zero and the B input is zero, the menu is automatically returned to the next level.)
