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 plural calculator can be+,-,*,+ =,* =, > =, < =, = =,! = arithmetic, which is based on complex > =, < = die



2 design input requirements of overloaded functions, can receive keyboard input from the plural form a+bi, the program can identify the real part and the correct assignment.



3 design computer test program, test the addition and subtraction, requirements in two digits, to test the multiplication, multiplication requirements for a number of operations.



4 design recording function, you can record different users using the calculator s situation, save the record in the form of a document in the computer, when the program is run for the username, display the user the previous record. The user records include: how many times do the number of addition and subtraction, multiplication, testing, 3 test average score, to replace the original recording user record new from the calculator program.
