1.串的长度
int strlen(char *str):
printf("%d\n",strlen(s1));//长度为14
printf("%d\n",strlen(s2));//长度为7
2.复制
char *strcpy(char *str1,char *str2):
strcpy(s4,s2);//把s2复制给s4
printf("%s\n",s4);//输出teacher
3.比较
int strcmp(char *str1,char *str2):
result=strcmp(s2,s3);
printf("%d\n",result);//s2>s3
4.字符串定位
char *strchr(char *str,char ch);
p=strchr(s1,'s');//p指向在s1中字符's'的位置
printf("%s\n",p);//输出student
5.子串查找
char *strstr(char *s1,char *s2);
p=strstr(s1,s3);//p指向在s1中字符's'的位置
printf("%s\n",p);//输出student
6.连接
char * strcat(char *str1,char *str2):
strcat(s2,s3);
printf("%s\n",s2);//输出teacherstudent
