arrays and validation (basic stuff)

Hello , I have been pulling my hair out for a week now. I am just learning to program. I have some code here, but i cant grasp 2 dimensional arrays, or moreover why this code doesnt work. Any help is appreciated.

//prog to allow supervisor to input 10 passwords and then allow user to try to
//login. Prog should tell user what level of access they have upon entering a
//valid password.Password will be 6 characters long.
#include <iostream.h>
#include <iomanip.h>
#include<string.h>

const int MAXIMUM =10;
const int CHARS=7;

void main ()
{
char Password[MAXIMUM][CHARS];
int i=0;

for (i; i<MAXIMUM; i++)
{
cout << "Please enter Supervisor password for level " << i+1<< " access ";
cin.getline(Password[i],CHARS);

if(strlen(Password[i])!= CHARS)
{
cout << "Invalid length";
cin.getline(Password[i],CHARS);
}
}
getchar();
}


this is only the first part but the debugger shows WEIRD stuff in password[]. Using Borland 5.Any tips for an aspiring ! learner?

have a look at the comments

//prog to allow supervisor to input 10 passwords and then allow user to try to
//login. Prog should tell user what level of access they have upon entering a
//valid password.Password will be 6 characters long.
#include <iostream.h>
#include <iomanip.h>

const int MAXIMUM = 10;
const int CHARS = 7;

void main(void)
{
        char password[MAXIMUM][CHARS];
       
        for(int i = 0; i<MAXIMUM; i++)
        {
                cout << "Please enter Supervisor password for level " << i + 1 << " access : ";

                cin.getline(password[i], CHARS);
       
                // this is where your problem is. cin.getline(password, CHARS) retrieves CHARS-1 characters max
                // because it null-terminates the string. so you'll only ever get 6 characters in the buffer.
                // what you should do is check to see if the length is == to CHARS - 1 like this:
                if(strlen(password[i]) != CHARS - 1)
                {
                        cout << "Invalid length";
                        cin.getline(password[i], CHARS);
                }
        }
}

By the way, there are other bugs in there... but i'll let you figure them out :)

Thankyou very much for your help. I will go and try that.And look for the other bugs as well-and this is only the start of my program.! LOL
