Getting errors while it seems it's all correct?

So, the problem is that I really don't know what I did wrong but I still get build errors:

I'd appreciate any help cause this is for school!
Thank you!
mutexe (2372)
Clue about the errors (the first two are warnings):
1
2
3
4
 
float a, V, O, d, D;
float a, b, c, V, O, d, D;
float a, b, B, v, V, P, O;
float V, O, r, pi;


also, do not use goto. Use a loop instead.

If mutexe's reply wasn't clear, switch cases do not create new scopes. You're trying to define the same variables in the same scope (main's local variables).

Oh, I understand now, thank you!
