I wanted to use g++. However, when I type in g++ in the terminal, it says, "fatal error no input files". I have asked a similar question before but to avoid extending the discussion in the comments, i have asked this solely for g++. I would also like to know the type of files that are compiled .i.e the nature of the file.
In Ubuntu you can append --help onto most commands to see more information about how to run them. In this case:
$ g++ --help
Usage: g++ [options] file...
Options:
....
You can also look at man g++ which will tell you lots more but here's the synopsis:
SYNOPSIS
gcc [-c|-S|-E] [-std=standard]
[-g] [-pg] [-Olevel]
[-Wwarn...] [-Wpedantic]
[-Idir...] [-Ldir...]
[-Dmacro[=defn]...] [-Umacro]
[-foption...] [-mmachine-option...]
[-o outfile] [@file] infile...
The short of it is you need to provide a filename to your source file. Eg:
g++ test.cpp
