Variables in void functions working with other void functions?
Is there a way to make variables used in a void function work in another void function.
for example:
I'm trying to get the someMath function to give the value of a (7) + x (5).
but whenever it adds these two variables, it never works correctly.
i know i can just simply put the vars in main and add them in main but i'm working on a project that relies on the use of variables that were created by other functions in new functions.
for example:

obj2 has the variables a and x so insted of
cout<<a+x try cout<<Obj2.a+Obj2.x also on line 6 and 7 put semicolon
Why create obj2? You can get rid of lines
and replace them with just

someNumber();
well thinking about it... int the project im working on someClass is actually in a separate header file.
someMath and someNumber are both member functions of someClass. A member function acts as though it is the object itself performing the action. So when you call
Here we have a dog that starts off dirty, licks itself, and ends up clean. Having the class in a separate header is irrelevant to this situation.
obj.someMath(); inside that someMath function it will act as obj. It's kind of hard to reason about with such obscure names, consider |

so what if void lickSelf() relies also on user input?
for instance (but a different example, going back to my example)
if you enter 5 for a and 7 for x would a and x keep their values?

im not really sure what im doing wrong here.
(this is a very small version of what im working on)
basically whenever i send ypdamf and epdamf to cout, i get 0 for both.

My assumption is that you are printing data from your class "Choosing_Class" when not in scope.
Choosing_Class is declare on line 37, and is only defined within that scope; in the if condition scope.
Some tutorials:
http://www.cplusplus.com/doc/tutorial/classes/
If both of the variables are available to the class, I don't see why they wouldn't be able to call each other...
Example:
In the above, set() calls three instances of prompt().

lets see... so
this shows:
lldb just started happening but going back to my code. after entering in 40 for (what is the variable) ylvl, i thinks ylvl = 1606406464
and after entering in 40 for what is elvl, the compiler thinks it is 0 which gives me the lldb because later when fightStart() is called, the math has a 0 in one of the denominators. :<

this shows:
list of races: 1.) Human what is your race?: 1 list of classes: 1.) Fighter what is your class (type n for next 10)?: 1 what is your level?: 40 Build your enemy: List of races: 1.) Human what is your enemies race?: 1 list of classes: 1.) Fighter what is your enemies class (type n for next 10)?: 1 what is your enemies level?: 40 (lldb) |

i also tried indexing the stats (yhp ymp ypatk etc and ehp emp epatk etc) in an array like this:
but this didnt do anything either because it still thinks yhp and ymp and all of those are different numbers outside of that specific void function

its almost like i have to create both the stats without having user input for enemy. which dosnt really seem... correct.
Why are there constant values for the HumanFGs, and why would you have a class with
then,
How can add have variable1 and variable2 if they are private?
also, could you put

1.) Why are there constant values for the HumanFGs, and why would you have a class with
class math
{
public:
void doMath()
{
cout << variable1 + variable 2;
}
private:
int variable1;
int variable2;
}
there are constants because if you look at the formulas, its the growthrate formula which im using to calculate stats for each character, and there fore, each formula needs a specific stat. i have a class like that because it needs to be called at a specific time. which is after one has chosen both their race and their class.
2.) how can add have variable1 and 2 if they are private?
because void add is in the same class, and therefore i can use it in that class and in that void function.
class math
{
public:
void doMath()
{
cout << variable1 + variable 2;
}
private:
int variable1;
int variable2;
}

Your classes are being declared within the scope of if's and functions; their data will not persist outside of those scopes.
A constructor, creating local data within itself will only be available to the constructor method.
As for your extensively long function, an alternative to your two functions; recursive:

It isn't that we are avoiding your main question, the point is that what you are attempting isn't going to work.
| Chooseing_Class a; |
Same applies for
| HuF fighterObj; |
Lines 39(choosing_class), 70(HuF) are local objects to those specific methods only.
Edit: Minor fixes.
