RE: [Dev-C++] Spaces in strings?

[<pr...@le...>]

Thanks Dany. But doesn't this limit my code in some manner? I've been
brought to believe that strings are better than chars since they
automatically adjust to the size of the input.

The best thing is to use a char array. Try this one:

#include <iostream>
#include <string>

using namespace std;

int main()
{
    char cName[80];
    cout << "Enter some words\n";
    cin.getline(cName,80);
    cout << "The word is " << cName << endl;
    system("pause");
}

Thanks Richard.
But I don't understand how the input stream being used by getline() (i.e.
cin) reads in spaces and tabs. Any explanations on that?

<code snippet>
std::getline(std::cin, name);
</code snippet>

yeah, you've gotten a few emails telling you to uses the getline function
rather tham cin.
basically cin will read the input string up to the first white space, this
is either a space(" ")or a tab("    ") or a enter( "/n" )
getline however will read everything including spaces and tabs up to the
first 'enter' or "endl"

  const int LEN = 80;
  char str[LEN];

  cout << "Enter string: " << flush;
  cin.getline(str, LEN); // use default '\n' delimeter
  cout << str << endl;

In the above example getline will just keep reading in characters
(whether they are tabs, spaces or anything else) until:

1) LEN - 1 characters have been read
2) it encounters the delimeter specified by the 3rd argument (which
    defaults to the newline character)
3) it reaches the end of the file

whichever happens first - see

RE: [Dev-C++] Spaces in strings?

[Ioannis V. <iv...@em...>]

My way of reading a sequence with whitespaces without size limit until a
'\n' character is found:


#include <iostream>
#include <string>

int main()
{
 using namespace std;

 string s;
=20
 while(cin)
 {
   char c;

   cin.get(c);
 =09
   if(c=3D=3D'\n')
     break;

   s+=3Dc;
 }

}


I know it is low level and I assume that there must be a better way =
(which I
do not know so far).

Ok everyone, I think we both need help to answer this.

I am also fairly new to C++ and that has always been the way I handle
strings. So far I have never had the need for very long strings. What
sort of length are we talking about here?

Any other suggestions anyone?

Cheers,
Dany.
