操作系统-简单登录系统

Question

我的目标是建立一个登录系统到我的操作系统。我试图检查两个值(用户名和密码)是否正确。我用的是

int login(char user, char pass, char userCorrect (int))
{
    if (user == "admin" && pass == "InHome123")
    {
        userCorrect = 1;
        printf(userCorrect);
        return userCorrect;
    }
    else
    {
        userCorrect = 0;
        printf(userCorrect);
        return userCorrect;
    }
}

为了获得用户输入和调用登录功能，我尝试了

char username[255];
char password[255];

int userCorrect = 0;


...


do
{
printf("| Lixt OS |\n");
printf("Username: ");
memset(username, 0, sizeof(username));
getstr_bound(username, strlen(shell));    

printf(username);

printf("Password: ");
memset(password, 0, sizeof(password));
getstr_bound(password, strlen(shell));    


printf(password);
printf("\n\n\n\n\n\n");

login(username, password, userCorrect);

}
while(userCorrect == 0);

当我运行我的操作系统时，我得到：ScreenShot1

最后那是什么S？我是在声明我的函数，还是说它错了？

Answer 1

所以，使用strcmp(var，correct_answer)

void NewSudo(char* b, int* sudo (int))
{

    // Vars

    char rootName;
    char rootPass;


    printf("Root Username: ");
    memset(rootName, 0, sizeof(rootName));
    getstr_bound(rootName, strlen(rootName));

    printf("\n");

    printf("Root Password: ");
    memset(rootPass, 0, sizeof(rootPass));
    getstr_bound(rootPass, strlen(rootPass));

    printf("\n");

    printf("\n\nConfirm authentication:\nRoot Name: %s\nRoot Pass: %s\n", rootName, rootPass);



    if (strcmp(rootName, "luis") == 0 && strcmp(rootPass, "pipoca"))
    {
        printf("Login Correct, SuperUser Loged-in\n");
        sudo = 1;

        return sudo;
    } else {
        printf("Login Failed\n");
        return sudo;
    }



}

然后做一次抽筋的动作：

int strcmp(const char *s1, char *s2) {
    int i = 0;

    while ((s1[i] == s2[i])) {
        if (s2[i++] == 0)
            return 0;
    }
    return 1;
}```

And put your func into your header file
