windows下使用:



Example usage:
  # Recursively check the current folder. Print the progress on the screen and
    write errors in a file:
    cppcheck . 2> err.txt
  # Recursively check ../myproject/ and don't print progress:
    cppcheck --quiet ../myproject/
  # Check only files one.cpp and two.cpp and give all information there is:
    cppcheck -v -s one.cpp two.cpp
  # Check f.cpp and search include files from inc1/ and inc2/:
    cppcheck -I inc1/ -I inc2/ f.cpp

可以发现内存泄露，变量未使用等等。。。
让我们向完美代码进发。。。
