原型:extern int strnicmp(char *s1,char * s2,int n);
用法:#include <string.h>
功能:比较字符串s1和s2的前n个字符但不区分大小写。
说明:strncmpi是到strnicmp的宏定义
当s1<s2时,返回值<0
当s1=s2时,返回值=0
当s1>s2时,返回值>0
举例:
// strnicmp.c
#include <syslib.h>
#include <string.h>
main()
{
char *s1="Hello, Programmers!";
char *s2="Hello, programmers!";
int r;
clrscr();
r=strnicmp(s1,s2,strlen(s1));
if(!r)
printf("s1 and s2 are identical");
else
if(r<0)
printf("s1 less than s2");
else
printf("s1 greater than s2");
getchar();
return 0;
}
