C语言：strcmp()—字符串比较

int strcmp(const char *s1,const char *s2);

#include <stdio.h>
#include <string.h> 
int main(void)
{ 

char *a = "English";
char *b = "ENGLISH";
char *c = "english";
char *d = "English";
//strcmp()只能比较字符串， 其他形式的参数不能比较 
printf("strcmp(a, b):%d\n", strcmp(a, b));//字符串之间的比较 
printf("strcmp(a, c):%d\n", strcmp(a, c));
printf("strcmp(a, d):%d\n", strcmp(a, d));
printf("strcmp(a, \"English\"):%d\n", strcmp(a, "English"));
printf("strcmp(&a[2], \"glish\"):%d\n", strcmp(&a[2], "glish")); 
return 0;
}

strcmp(a, b):1
strcmp(a, c):-1
strcmp(a, d):0
strcmp(a, "English"):0
strcmp(&a[2], "glish"):0
