I have another question if you dont mind me asking - (last one).

•

The arguments to the cin.getline function should be

a. format string and the buffer size.

b. character array and the array size.

If (b) was -array name and the array size- it would be accurate(?)
I think is (a) even if I dont quite understand why.

I dont write these questions.
Thanks for the replies...

It should be answer (b)
Here's an example:

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
#include <iostream.h>
main()
{
   char s[100];
   cin.getline(s,100);
   cout<<s; 
}
#include <iostream.h>
main()
{
   char s[100];
   cin.getline(s,100);
   cout<<s; 
}

So, cin.getline(char_array,max_lenght_of_array); :lol:
