Statements that start with # in C/C++ are known as preprocessor directives, that is, they are executed before compilation begins. OP has used a
#definewhich will replace any instance of A (IF(x)) with B (while (x)) in the code.So the
IFstatement is really just awhilestatement.But what is it in reference to? What's the "infamous if loop"?
"Infamous" just refers to newbies who sometimes call if statements "if loops". I've heard this quite a bit.
