    CODE#include

    main()
    {
    double factor;
    double resizer;
    double final;
    int end = 1;

    printf("RECIPE RESIZER\n");
    printf("Enter the factor:");
    scanf("%lf", &factor);

    while(end ==1)
    {
    printf("Enter an amount (or 0 to stop):");
    scanf("%lf", &resizer);

    if (resizer > 0)
    {
    final = (factor*resizer);
    printf("You should use %.2lf instead\n", &final);
    }

    else if (resizer ==0)
    {
    printf("Closing program...\n");
    end++;
    }


    //final = 0;

    }
    system("pause");
    }

    Umm.....

    I noticed that you use system("PAUSE") in your programming. You need to include stdlib.h for that function.
    You are better off using getchar(), explained in this website: http://www.gidnetwork.com/b-61.html

    It has been long time since I done any programming. I'm setting up an IDE right now. I'll run your program and see what is wrong with it.

    printf("You should use %.2lf instead\n", &final);

    take out the "&" next to final

    it works now

    Another thing I want to point out is that you use else if.

    "else if" is only used when you have 3 or more conditions. If you have 2 conditions then you use if/else or 2 if.
