VS2012 中strupr函数的问题

[JabinYan-TradeOff]

我使用VS2012运用strupr函数进行字符串大小写转换时出现问题。在生成解决方案时提示1>e:\daily study\vs2012\cstring使用\cstring使用\cstring使用.cpp(19): error C4996: 'strupr': The POSIX name for this item is deprecated. Instead, use the ISO C++ conformant name: _strupr. See online help for details.
好像在说strupr使用方式过期之类的。该怎么修改呐？新手上路，跪求高手指导！

用：_strupr_s

也可以自己写一个大写转小写函数。

谢谢高手建议，这是现在刚入门，还不会自己写，就是对着教材敲的这个程序，结果出了问题，不知道怎么修改。

用：_strupr_s

if(strcmp(strupr(input),password)==0) 这一句的strupr需要修改为_strupr_s吗？改了之后编译时又会报错。

在代码最前面加一行：

#pragma warning(disable:4996)

多谢！真的解决问题了，但是运行的时候还是有点小问题。不过还是万分感谢！

最好是自写一个，免去过期的烦恼

Locale Use the setlocale function to change or query some or all of the current program locale information. “Locale” refers to the locality (the country and language) for which you can customize certain aspects of your program. Some locale-dependent categories include the formatting of dates and the display format for monetary values. For more information, see Locale Categories.

您好：
我这句也为啥出现错误了？？

代码： strstr(_strupr_s(s),"LL")
