#include <iostream.h>
#include <iomanip.h>

using namespace std;

class CAT
     {
       public:
           CAT() {} 
           ~CAT() {}        
		  void Setname(char* name) { Name=name;}
		  char* Getname(){ return Name;}
          
       private:
         char* Name;
    };

    int main()
    {
       CAT Litter[3];
       int i;
	   char* name;
       for (i = 0; i < 3; i++)
	   {
		   name=new char;
          cin>>name;
		  cin.ignore (1000,'\n');
		  Litter[i].Setname(name);
	   }
       for (i = 0; i < 3; i++)
       {
          cout<<"Cat #"<<i+1<<": ";
          cout<<Litter[i].Getname()<<endl;
       }
     return 0;
 }


It stops printing after the 1st whitespace in each line.
Guidance and help is welcome.

Why are you allocating a character per time? (and never delete it)
You should use getline and C++ strings
nsw1216 (39)
Because i tried to it after the Litter[i].Setname(name); . There will be a debug error occured and the program not reponding.

Then if i use getline , i will only can print out the characters after the 1st white space.
here is my source code using getline.

If you allocate a single char, you will never get that right.
Use C++ strings
nsw1216 (39)
HOw should i write the code ?
Please provide me some guides.
Bazzy (6281)
change char* to string in declaration and then call getline(cin,name), not >>
Darinm (2)
Do it like this;
1
2
3
4
 
//...
string s;
getline(cin, s);
//...

Is it like this ?

 }

But i cannot compile it .
i wan to pass it to a function. Den return with a function.
Here are the compilation errors.

Remove the '.h' from included headers and try again.
nsw1216 (39)
Ok . It is working now. But when i put this part into my main program. i got some problem occured.
This is my program code.

I dunno y after i key in the nationality den the program keep on display the seating selection out nonstop. Is there any wrong in my code ?
Bazzy (6281)
Don't mix getline with >>, see http://www.cplusplus.com/forum/articles/6046/
nsw1216 (39)
Means i have to choose either one to be used in my program ?
Bazzy (6281)
With cin, getline is the best choice. You can mix them if you know how to do it but using only one is easier.
nsw1216 (39)
wat is the difference between get() and getline() ?
nsw1216 (39)
Why i change all my cin>> to getline() .
Compilation errors as below occurred .

Why like this one ?
Bazzy (6281)
If you are passing an int or other non string types to getline, read the link I posted earlier again.
nsw1216 (39)
Means how ? i dun understand it . Can you explain it by giving an example ?
Bazzy (6281)
That link shows an example
nsw1216 (39)
Okie i got it. But one of my input still cant pass into the function which is the 1st input use getline().
Here is my code. Help me check where it goes wrong .

I have a problem about the getline(). Why my 1st input will goes to the second output ad one while the 1st output is empty? Anyone can help check my code where it goes wrong ?
