Question

I have a simple Win32 console (no vcl) app written in Borland C++ 5, now I want compile the same application in VS 2010. but I’m new using this IDE and I don’t know how run the code in VS. I tried choosing Win32 Console Application. but even i very simple app like this

#include <iostream.h>
#pragma hdrstop

#pragma argsused
int main(int argc, char* argv[])
{
    cout << "Hello" << endl;
    getchar();
    return 0;
}

does not compile in VS.

So, What kind of VS 2010 C++ Project I must choose to compile a simple Borland C++ 5 Console app? or I need modify my app in order to use VS C++?

Answer 1

<iostream.h> is deprecated, and VS10 does not support it, use <iostream> instead, and you’ll also need std::cout, std::endl , etc.. i.e.

#include <iostream>    
#pragma hdrstop

// #pragma argsused // I don't believe this is valid in VS10

int main(int argc, char* argv[])
{
    std::cout << "Hello" << std::endl;
    std::cin.get();
    return 0;
}

Alternatively, if you don’t want to prefix your library uses with std::, you can put a using declaration at the top, after the headers:

using namespace std;
