1. 所设计的复数计算器可以进行+、-、*、+=、*=、>=、<=、==、!=运算，其中>=、<=是针对复数的模进行；

2. 设计输入重载函数，要求能接收从键盘输入a+bi形式的复数，在程序中可以识别出实部并正确赋值。

3. 设计计算器测试程序，对加减法进行测试，要求在两位数以内进行，对乘法进行测试，乘法要求为一位数的运算。

4. 设计记录功能，可以记录下不同用户使用计算器的情况，记录以文件形式保存在计算机内，程序运行时要求输入用户名，显示该用户以前的记录。用户记录包括：做了多少次加减法、乘法、进行测试的次数，后3次的测试平均分等，在退出计算器程序时用新的用户记录代替原有记录。

-1. The design of complex calculator can be+,-,*,+=,*=,>=,<=,==,!= operation, which >=,<= against plural mold carried out　

2. Design Entry overloaded functions, require it to receive input from the keyboard, the plural form a+ bi, in the process the real part can be identified and properly assigned.

3. Design calculator test procedures, test the addition and subtraction method, requiring less than double-digit carried out on the multiplication test requirements for a number of multiplication operations.

4. Designed to record, you can record different users to use calculator, recording the form of a document saved on your computer, the program runs when asked to enter a user name, display the user s previous record. User records include: How many times do add and subtract, multiplication, the number of tests, after three times the average grading tests, quit calculator program with the new user record to replace the original records.
