writing two programs in c++, one program is a lexical analyzer and the other is a top-down, predictive, recursive descent parser.

Everything needed to complete the assignments are posted, the assignments are connected, but two different programs.
Consider the grammar of “mini-language”, provided in file “grammar.txt”, and implement a lexical analyzer (a.k.a. scanner, lexer or tokenizer) for it Consider the grammar of “mini-language”, provided in file “grammar.txt”, and implement a top-down, predictive, recursive descent parser for it.
