Can someone tell me why this wont work?

This code is designed to let users create their own estimates for pricing and for some reason, the grandTotal function doesn't work right, any thoughts??

In what way does it not work? What are the values of hoursTotal, virusTotal, pCleanTotal, oSTotal, dataBackupTotal, dataBackupMDTotal, softwareInstallTotal, sHoursTotal and hHoursTotal at the point where grandTotal is calculated?

[Echo773]

they are supposed to be whatever the user ends up determining, if the cin of pClean is yes the PCleanTotal becomes 10 but if the user enters anything else it should be 0 and at the end it should add everything up, right now it always gives me -2 no matter what i do.

[Moschops]

== is not the same as =

[guestgulkan]

Why don't you make a function that checks whether a std:string
is equal to yes - in whatever combination/case the letters occur.
It would be neater than having all those
checks like

           if (virus=="yes"){
                virusTotal = 35;
    myfile << endl << "Price for virus removal: $35";
            }
            else if (virus=="Yes"){
                 virusTotal = 35;
    myfile << endl << "Price for virus removal: $35";
            }
            else if (virus=="YES"){
                 virusTotal = 35;
    myfile << endl << "Price for virus removal: $35";
            }
            else if (virus=="y"){
                 virusTotal = 35;
    myfile << endl << "Price for virus removal: $35";
            }
            else if (virus=="Y"){
                 virusTotal = 35;
    myfile << endl << "Price for virus removal: $35";
            }
            else{
                 virusTotal = 0;
    myfile << endl << "Price for virus removal: $0";
            }

scattered through the program.

[Echo773]

im not talking about that part, im having a problem with parts like

hours * 10 = hoursTotal; I think at least, can someone just try working it out? the rest of it works fine

[guestgulkan]

I wasn't really pointing out where the error was (although Moschops did point out an actual error) - I was merely suggesting a tidy up.

[Echo773]

ty guys

[Echo773]

where are you speaking of = not being equal to == i mean, yes i know but where am i using it wrong?

[Moooce]

I see it on line 229

[Echo773]

btw guestgulkan

i did fix that problem by using if (virus=="y" || virus=="yes") stuff like that late on

[Echo773]

solved changed grandTotal == to =
