Compiling C and C++ programs

1. Use an editor such as nedit, vim, or emacs:
   "nedit &" leaves the terminal window active

2. C programs: gcc filename.c -o filename
   (or gcc -o filename filename.c)

3. C++ programs: g++ filename.cpp -o filename
   (or g++ -o filename filename.cpp)

4. Running C and C++ programs: ./filename
   (This is how to run executable files)
