Thread: Help with truncation problem... Should be simple! :-S

Hi, I'm a complete new C++ newbie, I'm trying to graduate from batch scripting to real programming, and in doing so, also trying to convert some of my programs. This is of course long and laborious as I wade through the tutorials.
I'm sorry therefore if any of my questions seem obvious but as of yet I have very little idea what I am doing, so let me thank you in advance for your patience and help.

I'm trying to write some code to help me input single addresses, which will eventually develop into a program which will let me input an address and print it to a local printer. I'm struggling with the input though.

Here is my code so far, and what is wrong below.
Thanks

Code:

int main()
{

    cout<<"This program prints single address labels input by the user.\n\n";
    // address enter function
    // str length is 23 as 22+terminating.char "\0"
    char address[7][23];
    cout<<"Enter the address to be printed.\n";
    for ( int x = 0; x < 7; x++ ) {
        //Address input here
        cout<<"Line "<< x + 1 <<": ";
        cin.getline ( address[x], 23, '\n' );
    };
    cout<<"\n\nYour address was: \n\n";
    for ( int x = 0; x < 7; x++ ) {
        //Address output here
        cout<<address[x]<<endl;
    };
    cin.get();

I *need* the address to be 22 chars wide max. If I enter fewer chars, everything is fine (example 1) If I enter something which needs truncating, everything goes horribly wrong (example 2). It doesn't allow me to enter the latter lines, and rushes through till it finishes.

Example 1

Code:

This program prints single address labels input by the user.

Enter the address to be printed.
Line 1: Arthur Bond
Line 2: 34 Tepe Avenue
Line 3: Great Malvern
Line 4: Some Postcode
Line 5:
Line 6:
Line 7:


Your address was:

Arthur Bond
34 Tepe Avenue
Great Malvern
Some Postcode

Example 2

Code:

This program prints single address labels input by the user.

Enter the address to be printed.
Line 1: Sir Arthur Reginald Debug
Line 2: Line 3: Line 4: Line 5: Line 6: Line 7:

Your address was:

Sir Arthur Reginald De

Thanks, would this cause problems with the array if I put in more data than the array provides for? I was warned in the tutorial against trying to input more data than was allocated for in the array.

Sorted it, thanks for your help, prodding me in the right direction helped me find this.
(Sorry about the messy pasting, it's late, i'm tired and can't be bothered)

Code:

    string address[7];
    string addressin;
      getline(cin, addressin);
        address[x] = addressin.substr(0, 22);
