Answer 2

Explanation:

A label is a string of characters that pinpoint a location in a program. In most programming languages labels are of identifier type, usually continued by a "punctuation character".

The label serves as a destination point of a GOTO statement in most of the "high-level programming languages". Languages, like FORTRAN and BASIC, support labels of numeric type. The Labels can also used as a start point in compiled program statements during debugging.
