Why it works with an underscore?

[Generalx5]

NVM that last one I got it figured out, it was just a simple ";" mistake, I added an extra ; at the end of the text to replace.

Alright heres the new problem...

I have a bunch of if statements and they rely on a bunch of sensors,

when these sensors read a certain set of digital values it would turn on certain solenoids, correct, but! if these digital values from the sensors changed (knowing this from printf), the solenoids stay the same. They do not change with the input so I'm guessing that I'm doing something wrong with the if statements.

I have a lot of if's and in the very bottom on all the if statements, there would be an else if statement to eliminate any other undefined sensor readings.

any suggestions to what I'm doing wrong?

Ah! yes, I found the mistakes there, I've been reading the powerpoint tutorials from IFI and it got me confused. I start putting ; and brackets all over the place....I'll remember it for next time.

You can also use #define in your header files

#ifndef header_h__
#define header_h_

stuff stuff stuff

#endif

Then if you put #include "header.h" more then once it will say hey! header_h__ is already defined stupid! you can't define it again!! and just exit........

You could use a switch loop.

**Somebody please correct me if I am wrong, I don't remember is switch is only C++ or c too.
