creating a simple program to accept a password.

I just started learning c++ a few days ago and have come across a problem I can't seem to find a solution to. I figure one of you people with lots of experience well go "oh yah that's easy put such and such here and wala!" Anyway I am trying to make a program that asks you for a password and if you get the password right it says something and if you get it wrong it says somethings else. I have applications for this later down the road, but for right now I am starting simple.
Here is what I have so far...
#include <iostream.h>
#include <string.h>
int main()
{
char t[5];
cout<<"enter password: ";
cin.getline(t, 5, '\n');
if (t=="trey")
{
cout<<"you are a god"<<endl;
}
else
{
cout<<"you got it wrong! Haha!"<<endl;
}
cout<<"you entered: "<<endl<<t<<endl;
cout<<"the answer was trey"<<endl;
cin.get();

return 0;
}

I know I need to do something in line 8, but what I know not...If someone could help me I would greatly appreciate it.
Thanks in advance,
Trey

read that...

ok i read it...how would i aplly it to my program?

ok ok ok...i think i figured it out...thanks alot man...this one's been bugging me for several days...lol

howdy,
i went to the tut and started messing with it. it has an error - easy to spot though.

if(!strcmp(str1,str2)

should be

if(!strcmp(srt1, str2))

hope this isnt being to picky.
M.R.

then again, there is always the programmer-friendly version:

Code:

---

#include <iostream>
#include <string>

int main()
{
    string s1, s2("trey");

    cout << "enter password: ";
    cin >> s1;

    if(s1 == s2) {
        cout << "you are a god" << endl;
    }
    else {
        cout << "you got it wrong! Haha!" << endl;
    }
   
    cout << "you entered: " << endl <<s1 << endl;
    cout << "the answer was " << s2 << endl;
   
    return 0;
}

Here is a way to do it with asteriks. This will hide the password with asteriks as the user types it in.

Code:

---

#include<iostream>
#include<conio.h>

using namespace std;

void GetPassword( char* entry );

void main( void )
{
       
        char password[10] = "admin";
        char entry[10]    = "";
       

        cout << "\nEnter password: " << flush;


        GetPassword( entry );

        cout << "\nEntry....." << entry
                << "\nPassword.." << password
                << "\nStatus...." << (strcmp(entry, password) == 0 ? " passed " : " failed ") << endl;


}

void GetPassword( char *entry )
{
        int i = 0;
        char ch;

        while( 1 )
        {
                while( !kbhit() ); //** pause until kentered

                ch = entry[ i++ ] = (char)getch();

                putchar( '*' );

                if( ch == 13 ) //does not like '\n or '\0'
                {
                        entry[i-1] = '\0';
                        break;
                }
                else if( i == 9 )
                {
                        entry[i] = '\0';
                        break;
                }
        }
}

does the string class do away with the need for strcmp?

nope

yes because it has overloaded operators and its own set of compare member functions

is there a way to choose a char in the middle of a string(like temp[3])?

yes you can subscript a string with operator [] or you can use member fuction at()
