Linux Compile Multiple C++ Files

Compile Two Files:

$ CC -c Main.cc Sales_item.cc    		# by default generates a.exe
                                        # some compilers generate a.out

# puts the executable in main.exe
$ CC -c main.cc Sales_item.cc -o main

More efficient way is to only compile the modified file. Thus we need to compile original files into object files.

Link Object Files:

$ CC -c main.cc                     # generates main.o
$ CC -c Sales_item.cc               # generates Sales_item.o
$ CC main.o Sales_item.o -o main	# by default generates a.exe;
                                    # some compilers generate a.out
