strcmp strcpy的使用 char类型

//判断从控制台输入的密码是否正确

BOOL varifyPassWord(char passWord[] , int index)

{

BOOL result = YES;

int count = 3;

char originalPassWord[20] = {0};

strcpy(originalPassWord , allPassWord[index]);

//开始判断密码是否一样

while (1) {

if (strcmp(originalPassWord , passWord) == 0) {

result = YES;

break;//输入正确，跳出循环

} else {

printf("密码输入错误，请重新输入:\n");

count--;

if (count == 0) {

printf("24小时不能再输入密码\n");

break;

//程序此时应该结束

}else{

printf("还可以输入%d次密码\n" , count);

scanf("%s" , passWord);

}

result = NO;

}

}

return result;

}
