Which of the following is not a valid variable name?
NEWVARIABLE
VAR_1
_LPIC
2_VAR
Explanation & Hint:
The variable name “2_VAR” is not a valid variable name. In many programming languages and shell environments, variable names cannot start with a number. Therefore, “2_VAR” is not a valid variable name, while the other options (“NEWVARIABLE,” “VAR_1,” and “_LPIC”) are valid variable names. |
