2) use of gcc/g++

gcc is the GNU compiler collection, originally called GNU C compiler.
gcc is commonly invoked from the command line, like so:

gcc [ option | filename ]...

This is correct but, probably means nothing to you, one would normally use gcc like so:

gcc [flags] file1 [file2 [file3 ...]] [-o output_file]

where file1 file2 etc. are input files, either C source files or pre-compiled object file.
example: gcc foo1.c foo2.c -o foo

The default executable output file is a.out. When producing object files, the default output
for each input file has the suffix .o .
