Please test my calculator prog

**TechWins** · 10-06-2002

What you should do for updating your new versions is to put the new version on a new post and then to put the new version on you very first post. For the rest of the versions you should delete them off of your posts to make sure there isn't any confusion.

Btw, there is an error in your latest version. When I enter 10 at the beginning to do a Cube function it closes the program.

make that:
while (b==0)

otherwise it has the opposite effect.

I've made a calculator, too. It supports complex numbers, strings, vectors and matrices.

It parses a string like this : "sin (2+4/(4+3i))"

woops, damn i'm retarted ...

I did a selection Demo on this forum.. search for it.. it's pretty easy

Sang-drax> It is while(b == 0). I'll take a look and try out your calculator.

Ruski> Ok, thnx. I'll check it out. getch() doesn't work right. Here's the code:
/* ... various code here */
Selection code:
1] Redo
2] return to main menu
3] exit {Quit}
pick.choice = getch();
if(pick.choice == '1')
code();
if(pick.choice == '2')
begin();
if(pick.choice == '3')
quit();

After the math is done, you have to push any of the numbers before the menu shows, then it still doesn't work right.

TechWins> I fixed the press 10 and get quit bug you where having. I forgot to change the command for case 10. I am currently working on sin, but can't get the correct output. The source for it is in the attatchment *along with the other fixes*. I was planning on the trig functions yesterday, but I had to get off the comp. Good idea on the thread/new version thing. I'll start doing that for now on.

NOTE: To get the sin function, you have to enter 13 on the main menu. I haven't added that one in yet becuase it doesn't work.

P.S.: Thanks for all the advice, help, and whatnot so far.

sang-drax> your calc is pretty cool. how did you get the colors to work?? and i found a few bugs. PM me if you want me to let you know what they are.

**Quantrizi** · 10-06-2002

Ok, i sent you the P.M. Does anyone know of a different way to make a menu? I tried Ruski's way, and it worked if I didn't change anything *including the stuff on the menu*. But if I changed even the slightest thing, it gave me errors. 102 to be exact all saying "cout is an aboligious *or whatever* statement", or something like that. I took out using namespace std; and changed iostream to iostream.h

**RoD** · 10-06-2002

Code:

Ok, i sent you the P.M

i think he meant he found bugs in sang-drax's calc, maybe i am mistaken.

**Quantrizi** · 10-06-2002

He was, but he also found some bugs in my code *well, not bugs, but helped me fix my menu(s)*

**Ruski** · 10-07-2002

I think I know what could be the problem.. If you used gotoxy(); or SetColor(); you couldn't because those functions aren't in the C++ Functions, it's a user-made function so you'll have to include the header file

("function.h" or whatever it was..")
Good Luck

**Quantrizi** · 10-07-2002

Good point...heh. But, would you still have to include conio.o *gotoxy is in the conio header(s)*

**RoD** · 10-07-2002

A header must always be included to use a function that is located inside of it.

Aside from the above mentioned i didn't find much, i would usually be much more helpful but i am ripping out hair with my game haha.

**TechWins** · 10-07-2002

If the program is compiling without any errors then the neccesity for a header is non-existent. Meaning that if you're finding errors with the actual program and not the code it doesn't have to deal with your header files.

RoD> Ok, thnx. That's exactly the same way I feel right now *hehe*.

TechWins> I'm getting errors with the cout and cin stuff.

How would I let the user input decimal numbers *like 2.3, and etc...*
