Which of the following identifiers is a valid variable name?

  • Monte_Carlo
  • Monte-Carlo
  • Monte Carlo
  • Monte@Carlo
Explanation & Hints:

Generally, variable names must:

  1. Begin with a letter (uppercase or lowercase) or an underscore (_).
  2. Be followed by letters, digits, or underscores.

Based on these rules, let’s evaluate the given identifiers:

  1. Monte_Carlo: This is a valid variable name. It starts with a letter and contains only letters and underscores.
  2. Monte-Carlo: This is not a valid variable name because it contains a hyphen (-), which is not allowed in variable names.
  3. Monte Carlo: This is not a valid variable name because it contains a space, which is not allowed in variable names.
  4. Monte@Carlo: This is not a valid variable name because it contains an at symbol (@), which is not allowed in variable names.

So, the valid variable name is Monte_Carlo.
