C++/C conversion to just C

[Alterah]

Set a break point at

 int Finished = 0;

and step from there. The problem should show up after a couple of steps. Also...your formatting for the switch statement...seems rather odd to me. I would do something like:

            switch  (choice)
            { 
                // accesses the functions
                case 0: 
                    Finished = 1;                     
                    break;
                case 1: 
                    addition(&reward);                
                    break;
                case 2: 
                    subtraction(&reward);             
                    break;
                default : 
                    printf("Error in input\n\n");   
                    break;
            }

Sure, it is more lines of code, but imagine each of the cases requiring 10 instructions. I think the way I have it above would be more clear. But, that is just a personal preference.

But in my watches all it says is

Function arguements
Finished = no symbol "finished" in current context
choice = no symbol.... etc.

what is that telling me?? i declared them they are symbolizing something, so it should work right?

At this point, I'd review how you created your "project": Is the file you are editing actually part of the project? Are you sure you are editing the correct "main.c"?

It sounds like your program is compiling, but not the file you are writing. that, or not running the proper objects.

When these errors come up, and especially on small scale projects, I recommend you use "rebuild everything", just to make sure.

[Alterah]

Consider the following:

int main()
{
     int foo;
     bar();
}

void bar()
{
     // I have no knowledge of "foo"
}

This is what the message is getting at. Are you able to step through the code at all? I was able to step through the code, fix the error I found with the debugger, and run your code.

One thing you can try is this:

File > New > Project > Console applicate > Run through the wizard, name your project. Then, you will have new project. Just copy and paste your code into the new main.c file of that project. Build it, and try debugging that. Like monarch dodra suggested, your project may be set up incorrectly.

[chucker]

ok the problem was just at the while loop. had to get rid of ; and made it == instead of =. fml hahahaha.

well thank you everyone for coming on this journey with me. Conversion to C using pointers success!

On a final note does anyone know how to make the case selection letter selection like A) B) C) instead of 1 2 3 ?

Please format your code using [coe] tags as what you have posted is almost unreadable. use Go Advanced, select code then click '#'.

Help you about what? You haven't asked a question! If you want to convert this c++ code to c (why??) then as a starter for 10 you need to replace all references to the c++ classes (cin, cout, ifstream etc) with appropriate code using just the c library functions (printf, fread etc).

Hello..good day..can you help me,about this? c++ to c...

Did you read the whole thread?
There is a lot of opinions what and how to achieve it. What is the problem?

[Charmmanuel]

hello.. Im still a student... I need help on that code..to make it c function not c++ ..

[VictorN]

hello.. Im still a student... I need help on that code..to make it c function not c++ ..

I am confused...
What happens? "still a student" cannot read? "still a student" has no idea how tocompile C file?
