LGTM, I'll review and merge this by this evening |

Please revert the use of using namespace std. It is bad practice and it will create trouble at some point, if not now. See https://stackoverflow.com/questions/1452721/whats-the-problem-with-using-namespace-std for further reading.

Also refrain from shortening variables for no reason. It makes the code unreadable. s should be renamed to func_str, d should be renamed to depth, and ok should be renamed to plotted.

Same thing here, rename st to symbolTable and ef, eg to expr_fx, expr_gx

| st.add_constants(); | ||
| addConstants(st); | ||
| st.add_variable("x", x); | ||
| exprtk::expression<double> expr; | ||
| expr.register_symbol_table(st); | ||
| exprtk::parser<double> p; |

Same thing, rename the variables here as well

@saumya1317 Important: I would suggest you to wait until I merge both of the other PRs. You will have to resolve merge conflicts and thus I would suggest you to only start working on my requested changes once I merge the other 2 open PRs. I'll ping you here once I do that. |

This pull request adds multi-expression plotting capabilities to the graphing application, similar to Desmos. Users can now plot multiple mathematical expressions simultaneously, each with its own customizable color. The feature includes dynamic expression management (add/remove), individual enable/disable toggles, and support for both regular functions and parametric curves.
