<pre>
原型：extern int strcmp(char *s1,char * s2);
用法：#include <string.h>
功能：比較字符串s1和s2。
說明：
當s1<s2時，返回值<0
當s1=s2時，返回值=0
當s1>s2時，返回值>0
舉例：
// strcmp.c
#include <syslib.h>
#include <string.h>
main()
{
char *s1="Hello, Programmers!";
char *s2="Hello, programmers!";
int r;
clrscr();
r=strcmp(s1,s2);
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;
}
