Order Correction

#include <iostream.h>
#include <conio.h>

void CPost();

int main()
{
   CPost();
   getch();
   return 0;
}

void CPost()
{
   cout<< "Hello\n";
}

I have the following code. I have put CPost to its
own function in attempt to answer my own
question, it did not work, but I post it this way
anyway. My question is how do I force it to
Cout then GetCH. Currently it does GetCH then
Cout, which ... messes things up, and prevents
me from continuing on.

Your sample code doesn't work with my compilers, I have tried this succesfully:

/* don't use iostream.h header */
#include <iostream>
#include <conio.h>

using namespace std;  /* needs this namespace in order to use cout */

void CPost();

int main()
{
   CPost();
   getch();
   return 0;
}

void CPost()
{
   cout<< "Hello\n";
}

Use cin to read the characters.

cout & cin are tied together, so that things will work in order.

If you mix c-library methods with c++ streams, there there is guarantee on the order.

It works as:

This deals with the namespace problem pointed out by jaimie for the cout and changes your getch to getChar() from the C standard library


 #include <iostream>
 #include <stdio.h>

void CPost();

int main()
{
   CPost();
   getchar();
   return 0;
}

void CPost()
{
   std::cout<< "Hello\n";
}

I know I can use Cin but, I wanted to avoid that.
However, adding the namespace worked out
great, thanks jaime.

With <iostream> you should really use:

#include <cstdio>

I would recommend to use

void CPost()
{
   std::cout<< "Hello\n";
   cout.flush();
}

That definitively flushes the output stream.
