LaTeX's newcommand has the following syntax:
newcommand *{<FOO>}[<i>]{<TEXT>}
User command to define
FOOto be a macro withiarguments (i= 0 if missing)
having the definition<TEXT>. Produces an error ifFOOalready defined.
Normally the command is defined to belong(i.e. it may take multiple paragraphs in its argument). In the star-form, the command is not defined aslong
and a blank line in any argument to the command would generate an error.
If you define a command with at least one argument (i > 0), you can specify an additional (optional) argument before the definition <TEXT>. This optional argument will be used as the "default" value for a first optional argument to FOO.
So, as an example, consider
newcommand{FOO}[2]{<TEXT>}
This command has two mandatory arguments and is therefore used as FOO{<one>}{<two>}. However,
newcommand{FOO}[2][X]{<TEXT>}
takes two (2) arguments, the first of which is optional and has a default of X (if not supplied). You can use it as FOO{<one>} (which is equivalent to FOO[X]{<one>}) or FOO[<one>]{<two>}. Similarly,
newcommand{FOO}[1][X]{<TEXT>}
takes a single (1) optional argument that has a default value of X (if not supplied) and can be used as FOO (which is equivalent to FOO[X]) or FOO[<one>].
In your particular case,
newcommand*{name}[1][C]{<TEXT>}
defines name to (be non-long; that is, <TEXT> cannot have blank lines and) take a single (1) optional argument that defaults to C if not supplied. You can use it as name (which is equivalent to name[C]) or name[<one>].
