@androidi: using win32 console app project in VS2010:

 

#include "stdafx.h"
#include <iostream>
#include <string>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{    
    string entry = "";
    cout << "Please enter your name.";
    cin >> entry;
    cout << "Hello, " << entry;
    return 0;
}

I haven't coded in C++ for probably 6-7 years. Not too different from the C#:

using System;

namespace TestingCSharp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Please enter your name:");
            string name = Console.ReadLine();
            Console.WriteLine("Hello, " + name);
        }
    }
}

 

edit - oh wait, you wanted C and not C++? For a quick and dirty app, just use printf() and scanf().
