I need help creating this C++ parser program that follows these rules in the image below.

The image shows a grammar specification for a programming language, possibly for educational purposes. Here’s the transcription and explanation:

**Grammar Specification:**

- **P ::= S**
  - `P` is a program and is defined by a single statement `S`.

- **S ::= V = E | read(V) | write(V) | do { S } while (C) | S ; S**
  - A statement `S` can be:
    - An assignment `V = E`
    - Reading a value into a variable `read(V)`
    - Writing a value from a variable `write(V)`
    - A `do-while` loop `do { S } while (C)`
    - A sequence of statements `S ; S`

- **C ::= E < E | E > E | E == E | E != E | E <= E | E >= E**
  - Conditions `C` are comparisons between expressions `E`:
    - Less than `<`
    - Greater than `>`
    - Equal `==`
    - Not equal `!=`
    - Less than or equal `<=`
    - Greater than or equal `>=`

- **E ::= T | E + T | E - T**
  - Expressions `E` can be:
    - A term `T`
    - A sum of expressions `E + T`
    - A difference `E - T`

- **T ::= F | T * F | T / F**
  - Terms `T` can be:
    - A factor `F`
    - A product `T * F`
    - A division `T / F`

- **F ::= (E) | O | N | V**
  - Factors `F` can be:
    - An expression in parentheses `(E)`
    - An operation or post-increment/decrement `O`
    - A number `N`
    - A variable `V`

- **O ::= V++ | V--**
  - Operations `O` are post-increment `V++` or post-decrement `V--`.

- **V ::= a | b | ... | y | z | aV | bV | ... | yV | zV**
  - Variables `V` are lowercase letters from `a` to `z`, and can be followed by other variable names or similar structures, like `aV`, `bV`, etc.

- **N ::=
