VS2008中常遇的警告

[beierqaz]

每次写C语言时，只要涉及scanf就会出现如下警告

code\8-1\8-1\1.cpp(11) : warning C4996: 'scanf': This function or variable may be unsafe. Consider using scanf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
1> c:\program files\microsoft visual studio 9.0\vc\include\stdio.h(306) : 参见“scanf”的声明
这是为什么？
