Visual C++ versus standard c++ - visual-c++

Question

1) I have been working with standard C++ (CodeBLocks)and starting to move to Visual C++. When creating a console application the VS builds the following:
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
This is not the standard c++ syntax but windows version.
Now, is there a way to use the standard c++ syntax in Visual Studio C++ and avoid the above
sintax so as to use the standard?
I mean, using VS C++ be able to code something standard such as:
#include "<iostream.h>"
#include <stdlib.h>
int main()
{
int month, day, year;
cout << "Hellow World" << endl;
return 0;
}
2) I get in visual c++ error by trying to include very common libraries such as
#include "<iostream.h>". Any advise much appreciated. (using VS 2013 and comparing it with previous code in WnDEv).
3) I also attemted to use this with an empty project adding:
but when I build it InteliSense cannot open source file stdafx.h, IntelliSense identifier "cout" is undefined, IntelliSense identifier "cin" is undefined. Please help. thank you
#include "stdafx.h"
#include<iostream>
#include<conio.h>
void main()
{
//clrscr();
int number, count = 0;
cout << "ENTER NUMBER TO CHECK IT IS PRIME OR NOT ";
cin >> number;
for (int a = 1; a <= number; a++)
{
if (number%a == 0)
{
count++;
}
}
if (count == 2)
{
cout << " PRIME NUMBER \n";
}
else
{
cout << " NOT A PRIME NUMBER \n";
}
//getch();
}

The inclusion of "stdafx.h" is because Visual C++ by default uses pre-compiled headers, and for that to work the first non-comment line in the source file have to be that inclusion.
For the _tmain function, it tells me you have opted to make a WIN32 console project. You can make an empty project, and add files manually as needed, and use only standard C++ features, like having the proper main function instead.
