The totalcost in the main function is not adding charges1, charges2, and charges3. Its outputting a random very very huge number, anyone know what i did wrong the code or calculation to fix this problem.

This shouldn't even compile... Unless I'm missing something?

There is no declaration of main that takes double, double, double (line 209)

It compiles without any warnings or errors, im passing the charges1, charges2, and charges3 to the main function from the classes, when i run it, all the charges variables get updated and display the correct amount its just that totalcharges variables that not displaying right, if anyone you can see why, or give me a better solution to pass those variables, i would appreciate it.

I found the problem, i also had to make the void function take and pas the charges to main. heres the code that works correctly now.
