If the file is not present then it creates a new text file. To device and intermediate drivers, a file object usually represents a device object. For most library systems, creating object files that become part of a static library is as simple as creating object files that are linked to form an executable: Shared libraries, however, may only be built from position-independent code (PIC). If your entire program is in one source code file, you can instead do this: % g++ foo.cc -o foo This tells the compiler to run the preprocessor on foo.cc, compile it If calling code specifies dynamicFile.Sample(StringSearchOption.StartsWith, false), the dynamic class searches for "Sample" at the start of each line, and does not remove leading and trailing spaces.
