    Build error

    When I build this program, I get an error message; not from Visual Studio, but from my computer. Can anyone help me?

    Code:

    Code:
    while (totaldays1 < 29)
    	{
    		outfile1 << name1 << '\t' << (loanAmount1 + interest1) << '\t' << (28 - totaldays1) << endl;
    	}
    When do you expect this loop to stop?

    Oh, I get it now. But I wasn't trying to loop it, I'm trying to set a condition statement; how would I set that up?

    You would probably have to assign a meaningful value to totaldays1. Then if you want to make a decision, you generally use if.

    I changed the code:

    Code:
    if (totaldays1 < 29)
    	{
    		int totaldays1;
    		outfile1 << name1 << '\t' << (loanAmount1 + interest1) << '\t' << (28 - totaldays1) << endl;
    	}
    but it still gives me the error

    what is an error?

    also note that
    Code:
    if (month3 = 1 || 2);
    does not do what you expect (and your program full of it). it should be

    Code:
    if (month3 == 1 || month3 == 2)
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.
