Is there a way to display the variable name instead of its value? for example, I need something likevarname = 1; function[varname]; and the output is varname instead of 1

varname = 1;

SetAttributes[ShowName, HoldAll]

ShowName[name_] :=
 Row[{"The name is ", HoldForm @ varname, " and its value is ", ReleaseHold @ varname}]

ShowName @ varname

The name is varname and its value is 1

Or simply

HoldForm @ varname

varname

    $\begingroup$ Why not just say ShowName = HoldForm? $\endgroup$ – Michael E2 Sep 16 '14 at 13:20

There's also Defer to accomplish this:

varname = 1;

Defer @ varname

varname
