Thread: 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);

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);

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.

It doesn't seem to work using the change this: to this: in my compiler... I don't know why... again, I'm using borland c++.

Can you please post your latest code and what the error message is?

//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[]="GETKEYS";
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))
{
Change this:
cin >> chc1;

To this:
cin.getline(chc1,20);
cout << "YOU NOW HAVE THE KEYS." << endl;
}
else if(strcmp(chc1,getkys))
{
cout << "YOU HAVE NOTHING.";
}
}
}
//errors:
//undefined symbol "change"
//statement missing ; in function main
//undefined symbol "to"
//statement missing ; in function main

Can you show me some full sample code of how this might work?

Code:

//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[]="GETKEYS"; 
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.getline(chc1,20); 
if(!strcmp(chc1,getkys)) 
{ 
cout << "YOU NOW HAVE THE KEYS." << endl; 
} 
else if(strcmp(chc1,getkys)) 
{ 
cout << "YOU HAVE NOTHING."; 
} 
} 
}

Thank You,
It worked. Now I can conitinue with the game I'm creating.

Whew ... I was starting to get worried there!
