    Question Comparing Chars

    I'm using Borland C++. How would I go about having a space when using if(!strcmp(chc1,getkys))? Here is a sample of my code:

    //The Highlight Problem Is The getkys variable


    //Filename: lv1.cpp
    //Function: Level 1
    #include <iostream.h>
    #include <conio.h>
    #include <stdlib.h>
    #include <string.h>
    void main()
    {
    int keyamt=0;
    int lp=1;
    unsigned char chc1[20];
    unsigned char getkys[]="GET KEYS";
    unsigned char getchc[20];
    unsigned char inv[]="INVENTORY";
    cout << "LEVEL ONE" << endl;
    cout << "ESCAPE FROM THE DUNGEON" << endl;
    cout << endl << "YOUR IN A DARK DUNGEON CELL." << endl;
    cout << "THE WALLS ARE COVERED WITH MOSS AND COBWEBS." << endl;
    cout << "THE SLEEPING GUARD SEEMS EXTREMELY VULNERABLE" << endl;
    cout << "A PAIR OF KEYS ARE ATTACHED TO HIS BELT." << endl;
    while(lp!=0)
    {
    cout < ">";
    cin >> chc1;
    if(!strcmp(chc1,getkys))
    {
    cout << "YOU NOW HAVE THE KEYS." << endl;
    }
    if(strcmp(chc1,getkys))
    {
    cout << "YOU HAVE NOTHING." << endl;
    }
    }
    }

    You could use getline().

    >cin >> chc1;

    Change to:
    cin.getline(chc1,20);

    Question Understanding

    I don't specifically understand that... Can you put it in more specific words? Maybe a more specific example? And what header file do I need?

    Change this:
    cin >> chc1;

    To this:
    cin.getline(chc1,20);

    Unsigned char?

    Exactly what does it mean when you declare a character to be "unsigned"?

    I thought that only had to do with variables of type int.

    use some delimeter in the getline()

    cin.getline(chc1,20,'\n');
