strcmpi,stricmp函数
函数原型:extern int strcmpi(char *str1,char * str2)
或者 extern int stricmp(char *str1,char * str2)
参数说明:str1为第一个要比较的字符串,str2为第二个要比较的字符串。
所在库名:#include <string.h>
函数功能:比较字符串str1和str2,但是不区分字母的大小写(这点就是与strcmp的区别)。
返回说明:返回整数值:当str1<str2时,返回值<0; 当str1=str2时,返回值=0; 当str1>str2时,返回值>0。
其它说明:暂时无。

在VC++ 6.0 编译运行:
显然当str1与str2比较后,由于str1是str2的子串,故而str2的字典序比str1要大,返回值<0。
