If you're running Windows then make use of this:
g++ -o program program.cpp
g++ is the name of the compiler and -o is the option needed for creating a .o file. Program (without .cpp suffix) is the exe file and program.cpp is your source file that you want to compile.
g++ -o program program.cpp&program.exe
Use this shortcut to run the .exe file of the program. This may run in Ubuntu but you may have to use .out suffix instead of .exe. Use this handy batch script I made to execute your programs on Windows:
@echo off&&cls
set /p pathName=Enter The Path where the file is located:%=%
cd %pathName%
REM set /p exec=Enter The Name of the executable you want to make:%=%
set /p file=Enter The Name of the file you want to compile:%=%
g++ -o %file% %file%.cpp
%file%.exe
save it as cppExecutor.bat
Also you could use the following commands on Unix (Linux and Mac) OS:
CC program.cc
If you want to use gcc:
gcc -o program program.cpp
With the shortcut:
gcc -o program program.cpp&program.exe
