C # simple calculator for WinForm developed in language,
The last C # lab class required the development of a Windows-based WinForm calculator to implement basic operations such as addition, subtraction, multiplication, division, and so on. There are many problems with the reference documentation, and the floating point number cannot be calculated (I really don't know what is the division function at this t
The Set calculator assists java in processing the alignment connection of structured text, and java structuring
The database has associated statements to facilitate alignment and join operations. However, sometimes data is stored in text files. To use JAVA for direct computation, you need to write a large number of loop statements, code is cumbersome and inefficient. Java programming is assisted by the set calcula
Homework:Use regular expressions and recursion to implement the calculator function.Realize:1, the implementation of the calculation of parentheses2, achieve the index, subtraction and other functionsFirst, the example illustrates:This instance wrote a version of itself, but there is still a little bug, example:-2-2 and other computational problems, so finally in the code based on Wu Sir added index, to seek redundancy and other functions.The
The Set calculator assists Java in processing conditional filtering of structured text, and java structuring
Using Java to filter data in text files by conditions may cause the following troubles:
1. files are not databases and cannot be accessed using SQL. When the filter conditions change, you must rewrite the code. If you want to implement SQL-like flexible conditional filtering, You need to implement dynamic expression parsing and Evaluation on yo
