Abstract: When writing program code, syntax errors can be detected and a diagnostic error message can be provided. One of the causes of errors in a C-based programming language such as but not limited to C++ is a missing definition. The definition can exist in a file that is separate from the source program file. The file may be designated by a particular statement such as a “#include” statement which points to the file in which the token used in the code is defined. The list of files and their relationships form an include graph. A feature inside an IDE can suggest potential “#include” statements to correct a missing “#include” statement error. By using the include graph a more accurate list of potential corrections can be suggested so that standard and platform independent code can be written.
