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 ::=
