First, run code analysis
Run code analysis results are as follows:
1> ------ Rebuild All started: Project: suduku_without_gui, Configuration: Release Win32 ------
1>header.cpp
1> interpretor.cpp
1>SudokuChecker.cpp
1>SudokuMaker.cpp

========== Rebuild All: a successful, 0 failed, 0 skipped ==========
Second, the problem summary
1. file encoding format is incorrect
Problem Description
> E: \ github \ software_engineering_sudoku \ suduku_without_gui \ suduku_without_gui \ interpretor.cpp (1,1): warning C4819: The file contains a character can not be represented in the current code page (936) in. Please save the file as Unicode format to prevent data loss
the reason
Project documents are saved in UTF-8 with signature format, the file is UTF-8 encoding without signature.
solution
Save the file as UTF-8 format
2. sign mismatch
Problem Description
E: \ github \ software_engineering_sudoku \ suduku_without_gui \ suduku_without_gui \ SudokuReader.cpp (73,59): warning C4018: ">": signed / unsigned mismatch
the reason
SudokuReader::num_bytes_of_sudoku_infile * BUFF_SIZE > n_bytes_read
It is greater than the number of type int left, and right is DWORD comparison operator type, is unsigned long type DWORD
solution
Since ensures SudokuReader :: num_bytes_of_sudoku_infile * BUFF_SIZE not exceed represented by an int, so it can be lifted up as a DWORD type is not recommended n_bytes_read cast to type int, to avoid unnecessary errors.
