Calling functions in IF-ELSE

[system]

dxw00d:
You cant have variables and functions with the same names.

long low1,

 void low1()

long low1, medium1, high1, low2, medium2, high2, low3, medium3, high3;

...

void low1()
 {
   disbackleft = disbackleft < 3;
 }

As the compiler said, first you declare low1 as a long, then as a function. Make up your mind what you want "low1" to be.

thanks,already delete the declaration..now the problem is to call any equations into if else..

 if(disbackleft = low1() ...

This is not correct. This is assigning, not comparing. I suggest you Google a C tutorial.

thank u..basically i want replace equation (example:x<a && x>b) with a word (such as 'low')..any idea to do that?
