‘cout’ is not something you do. It is a global variable, which is an instance of the
std::ostreamtype. You could say e.g. “output tocout“.#definedoes textual substitution. It is basically the same as if you used search-and-replace in your text editor to replaceBLAHwithword. Thus, the linecout << BLAH;turns intocout << word;. If it’s not working, it’s becausecout << word;isn’t a valid statement in that scope. The preprocessor does not care about any of the surrounding text. It has basically zero understanding of the code (it knows how to tokenize the code, i.e. break apart operators and other punctuation if you don’t put in any space, but that’s about it.)
