Hi mahmoodn, > What is translation unit and how can I determine how many translation unit > my code have? :confused: Let's say you have three source code files, foo.cpp, bar.cpp and baz.cpp. Here are the three translation units, which translate from the source file to the object file. g++ -c foo.cpp -o foo.o g++ -c bar.cpp -o bar.o g++ -c baz.cpp -o baz.o When linking the object files together, that process is not a translation unit. g++ foo.o bar.o baz.o -o quux HTH, --Eljay
