    #include "stdafx.h"
    #include <iostream>;
    
    using namespace std;
    
    using namespace System;
    
    
    int _tmain(int argc, _TCHAR* argv[])
    {
    	int city1 = 0;
    	int city2 = 0; 
    	int averageTemp= 0; 
    	cout << "Enter the name of city 1:";
    	cin >> city1
    	cout << "Enter the name of city 2:";

    stdafx.h is not a "standard" file (despite its name). It is produced by Visual Studio when you set up a project.

    If you are not compiling your code within a project set up by VS, then it won't have such a file. Either remove it or make an empty file with that name.

    System is not a standard namespace, so I'm not sure how you expect it to recognize it. Seeing as your code doesn't appear to use anything beyond what is in the std namespace, I don't see a problem with removing that line altogether.

    You also don't need a semicolon after #include.
