您可能想要使用strcmp：
#include <stdio.h>
#include <string.h>
int main(int argc, char **argv)
{
int v;
const char *str1 = "hello";
const char *str2 = "world";
v = strcmp(str1, str2);
if (v < 0)
printf("'%s' is less than '%s'.\n", str1, str2);
else if (v == 0)
printf("'%s' equals '%s'.\n", str1, str2);
else if (v > 0)
printf("'%s' is greater than '%s'.\n", str1, str2);
return 0;
}
