Program started running, require the user to enter first two operation.
Then the menu option, undertake corresponding tarsus operations.
Analysis in this paper shows that: because of the large range is too big, can not directly defined as int or float,
So our idea is defined as a string literal,
The number of input a a deposit to string array inside.
And then in the operation of time also is a a ground operations.
This process will have to from the most basic mathematical algorithms, starts to there is no lack of judgment.
Involves the application of array and pointer. The most difficult judgment is feeling
Conditions and application array pointer and appeared in the process of many unforeseen predictable wrong,
Still have to go through gradually debugging slowly find out. We start from the first addition and subtraction, however
In the two after a method based on the mentalistic and high factorial method.
More trouble is subtraction and division, and because of the transf
