Einstine calculator Mark 2
Hi again, took the advice given to me and last night in I played around with the code trying out different things until I came to the code below. I did try putting in do while loop before the switch but kept getting a error, so could some tell me were to put it? I tidied up the code a bit too. I think there no more mistakes now.I would have fixed the program the first time but I lost the disk with the code and as I said I just found it.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
