Can anyone expalin to me better "What is the diff between if and #if?" I thought i read that maybe its because #if can only be used with constant conditions, is that correct. Someone told me that #if is faster and improves program readability than if does but connot be nested, is that true?
Some please enlighten me?:D
if is a part of the c language. #if is a part of the c preprocessor language.
i've noticed a pattern of you starting threads asking the difference between things that aren't very related to eachother.

Thanks for your input!:D
#if is what we call a preprocessor directive...for more information try here.
if is simply a C/C++ (and Java) keyword - a reserved word in the C language that cannot be used as a variable name. Your compiler recognises if as a conditional statement.

Yes, that is correct.
"if" is a statement-- part of the defined c language. "#if" is also called a compiler directive -- it is used not for code, but to tell the compiler to do something during compilation.Quote:
