Talk:Undefined variable

The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.

The original definition given was this:

An undefined variable in a computer program is a variable name that is called by the program but which has not been previously assigned a value by that program.

I think that would describe an "uninitialized variable". For example,

// C
int x;
printf("%d", x);
// x is declared but uninitialized

// Java
Frame x = null;
x.show();
// x is declared but set to null

Some clarification may be needed of the terms

undefined variable
undeclared variable
uninitialized variable
NULL (C), null (Java(, nil, or undef (Perl) as in reference or pointer type.

I totally agree. "Definition" == assignment. This article describes, as its first sentence even suggests, undeclared variables. --pfunk42 11:41, 9 November 2006 (UTC)[reply]
