Help with adding users

Expand Post »
Hey, everyone. I am having getting my code to work. I have tried to add in a selection for the users. Not to mention I think I broke my table.

here is the errors I get.

Re: Need Help!!!

exit? It's a reserved word for a standard function, and you have not declared it otherwise.

Work on your bracing.

Re: Help with adding users

you need an opening brace { between lines 53 and 54 (or at the end of line 53 if that is your coding style) and remove the semicolon at the end of line 58.

lines 78, 81 and 85. values is a 2d array of doubles and you are attempting to use them as if it is a 1d array.

You really need to start reading the error messages better and try to figure out what's causing them. The first error message for any given line number is usually the most important as the compiler will spit out several other error messages as well.

Re: Help with adding users

Yea, I couldn't figure out how to fixed that error. Far as the lines I need to find out in Visual C++ 2005 express to display numbers to figure out which number line that is. Thanks for the help let me look that up.

Re: Help with adding users

Ok I figured the line numbering out. I still can't get rid of this error.

error C2181: illegal else without matching if

I thinking my syntax is all wrong.

Re: Help with adding users

>>Far as the lines I need to find out in Visual C++ 2005 express to display numbers to figure out which number line that is
Just click on the error message and the IDE will move the cursor to the correct line. Also the current line number is always displayed at the bottom of the window.

>>error C2181: illegal else without matching if
I already told you what that error was -- missing opening brace {.

Re: Help with adding users

No it isn't correct. Read my post #5 very carefully, the very first sentence told you where to put that brace. If you count the braces in the code shipped you just posted you will see that there is an opening brace missing. The opening brace at the top of your last post is misplaced. Move it down to where I told you it belongs.
