Re: [Dev-C++] using strings

[Jason H. <jas...@bt...>]

Hi, your problem is that you are mixing up the string header for the C =
string functions i.e. strlen(), strcat(), etc... and that for the string =
object which is part of C++.

#include <string>

Is the one you want. Note the lack of the ".h"; this has become standard =
in C++. Also <string.h> and <cstring> (no ".h") are the same header.... =
well, almost but it makes no difference in the current mingw version. =
All the old style C headers i.e. <stdlib.h> <stdio.h> have now been =
moved on to the new form in C++ i.e. <cstdlib> <cstdio>, and the old =
form is depreciated, but still usable at the current time.

Basically you can just delete all the .h's off the includes in your code =
below.

Jason.

  Subject: [Dev-C++] using strings


  Hello,
  A seemingly simple problem has stumped me so far.  I cannot figure out =
how to use simple strings in my programs.  Do I need to add the =
<cstring.h> library?  If so, my compiler says it can't find it- can I =
download this somewhere?  I know I can get around this problem by using =
an array of chars, but I want to be able to use strings.  I am using Dev =
4.01 and the mingw compiler 2.95.2-1.  A thousand thanks for any help.

  When I try to compile this program, I can a 'string' undeclared (first =
use this function) error.
  // start

  #include <iostream>
  #include <iomanip>    // For setw()
  #include <fstream>    // For file I/O
  #include <string>

  using namespace std;

  int main()
  {=20
    string s1;
    char pause;

    cin >> s1;
    cout << endl << s1 << endl;
    cout << "pause";
    cin >> pause;


   return 0;
  }
