ex2.cpp

ex4.cpp

Explanation / Answer

save ex2.cpp and ex4.cpp.

-------------------------------------------------------------------------------------

at command prompt type vi Makefile and paste below code and save.

//makefile

ex2:ex2.o
   g++ -o ex2 ex2.o
ex2.o:ex2.cpp
   g++ -c ex2.cpp
ex4:ex4.o
   g++ -o ex4 ex4.o   
ex4.o:ex4.cpp
   g++ -c ex4.cpp
clean:
   rm *.o ex2 ex4 -rf backup
backup:
   mkdir backup
   cp ex2.cpp ex4.cpp backup

----------------------------------------------------------

crate tar in present directory where ex2.cpp , ex4.cpp and Makefile present

tar -cvf ex2.tar.gz *.cpp Makefile

then if you type below command , it works

$ tar xvfz <userid>.ex2.tar.gz

$ make

$ ,/ex2
