如何在 Visual Studio 2005 中获得 printf 警告? [英] How to get printf warnings in Visual Studio 2005?

问题描述

当给 printf() 提供错误数量的参数时:

When providing the wrong number of arguments to printf():

printf("%s", "foo", "bar");

或者当提供错误类型的参数时:

or when by providing arguments of the wrong type:

printf("%d", "foo");

gcc 能够警告这些错误:

gcc is able to warn about these mistakes:

$ gcc -Wformat printf_too_many_arguments.c
printf_warnings.c: In function `main':
printf_warnings.c:5: warning: too many arguments for format
printf_warnings.c:5: warning: too many arguments for format

$ gcc -Wformat printf_argument_of_wrong_type.c
printf_warnings.c: In function `main':
printf_warnings.c:5: warning: format `%d' expects type `int', but argument 2 has type `char *'
printf_warnings.c:5: warning: format `%d' expects type `int', but argument 2 has type `char *'

如何使用 Visual Studio 2005 获得此类警告?

推荐答案

我使用 cppcheck (http://cppcheck.sourceforge.net/) 使用 Visual Studio 2005 时，它会检测提供给 printf/wprintf 的参数数量与所需参数数量之间的不匹配.

I use cppcheck (http://cppcheck.sourceforge.net/) when working with Visual Studio 2005 which detects mismatches between the number of parameters provided to printf/wprintf and the number of parameters required.

不幸的是，它没有检查类型是否匹配，但这只是一个开始.

Unfortunately it doesn't check the types match, but it's a start.
