RE: [Dev-C++] BAKERY PROBLEM

We are talking about C++.

<cstdlib>, <cctype> e.t.c. have the C library functions defined in
namespace std. So, if you want to use printf using <cstdio> you should
write:

#include <cstdio>

int main()
{
 using std::printf;
// or using namespace std;
printf("Hello World!\n");
}

If you use <stdio.h> e.t.c. you do not need to use the using statement.
For example:

#include <stdio.h>

int main()
{
 printf("Hello World!\n");
}


The C subset header files of C++ with the .h extension are defined with
something like this:

--- stdio.h ---

#include <cstdio>
using std::printf;
// ...


Now C++ standard library uses only headers without extensions with the
need of using statement.

For example:

#include <iostream> // Correct

// ...


#include <iostream.h> // Incorrect in ANSI C++ (1998)!



Hope this helps.

Hi,
I took a look at Vassili's solution.
At the beginning of the (attached) file there are the lines:

-----------
...
#include <cstdlib>
#include <cctype>

-----------

I would have included the files: stdlib.h and ctype.h instead of cstdlib

and cctype.

Is there anything wrong with my approach?
