Thanks, I'm making it for work to make figuring orders easy lol. I'm very new to coding though, just using the basics I've learned so far, which isnt much lol

My inputs are:

Answer 7

I just fixed it so you can run it with my inputs to see the output. I dont understand because it says the error is on line 77. Which is in comments..

Answer 9

This is with nothing commented

Answer 10

It works, what did you change if I may ask? The only issue is on line 147. It didnt assign 'double lastpnlfc' to the value of 'lastpanelwidth + foam + 0.5

Answer 11

Ohhh, okay, how come it is showing up as 0.0 though if I have it changing the variable?

Answer 12

I think the problem was that you were calling a local variable outside its local environment, this returns the 'symbol not found' error which basicly means you tried to use a variable that wasn't declared. I haven't read the whole code so I might be wrong

Answer 13

Declare every variable right after main() or declare them with the inputs. You also have to get rid of most of the 'double' declarations, since they are already declared

Answer 14

double lastpnlfc = 0;
double lastpnlbk = 0;

double samevinylsizes = 0;
double firstpanelvelcro = 0;
These are variables defined before their usage

if(panels == 1) {
samevinylsizes = 0;
} else if(panels == 3) {
samevinylsizes = 4;
} else if(panels == 5) {
samevinylsizes = 8;
} else if(panels == 7) {
samevinylsizes = 12;
}
Notice how there aren't any double declarations, this is because we defined them before and thus don't need another declaration

You defined a diffrent variable every time you checked the if's, these are local variables and don't work outside their curly brackets

Answer 15

Lastpnlfc is autodefined as 0. This changes on line 141, but this line is never run because lastpnlwidth equals 24. So lastpnlfc stays 0
has it to be 26.5?

Answer 16

Good luck with your code
