//To compile: g++ [source_code.cpp] -o [exec_file]
// replace [soure_code.cpp] with the filename, 
// replace [exec_file] with the executable file name
// i.e., g++ c++_basics.cpp -o run
//Note: if the output redirect is not given, i.e., the "-o [exec_file]" part is missing
//      then the default executable name is a.out

//To run the program, simply run the executable: ./[exec_file]
// i.e., ./a.out  (if your executable file is a.out)
