This is not possible at the moment (and not sure it will ever be possible) :)

Ahoy Caironauts,

  How can I define two functions with the same name but not the same arguments, e.g, 

- `func test()`
- `func test(param: Uint256)`

It is possible in Solidity and I'm trying to find the Cairo equivalent.

How can I define two functions with the same name but not the same arguments?

Another vanilla Cairo question, what are the sorts of references, i.e. ids that can be modified by hints? relatively important to work against an evil prover

presumably not locals or tempvars, but say, implicit references, or the two(?) kinds of let statements (expressions and references)

maybe if there's some documentation i don't know about re: all the id types, relocatable values and so on,

also maybe, is there a pattern that can be used for function pointers?

Another vanilla Cairo question, what are the sorts of references

I have a question about how to print "Hello World" in Cairo 1. How do I log/print ?

How do I log/print in Cairo 1.0?

该从该从哪里哪里开始开始学起学起呢呢？？PythonPython嘛嘛？？

Hey guys,
I got this error `The return type of storage variables must be a felts-only type (cannot contain pointers)` when when compiling this:
```
struct MultipleLinear {
    number_of_features: felt,
    coef_s: felt*,
    intercept_: felt,
}
@storage_var
func solution_storage(address: felt) -> (solution: MultipleLinear) {
}
```
Apparently **storage can only return felt**? So what would be the solution if I want it to return an array or a struct that contains felt*?

storage for array

Howdy.


I am trying to dev against the starknet devnet to build my frontend and am experiencing some issues. With argent, it seems that the version in the chromestore isn't up to date with the devnet's fee token, so I can create an account and fund it, but still not be able to do any transactions.


When I try to build from source, I get an error about something involving a react server or something.


Trying braavos, I am able to transact against dev net (invoke method calls) but calling views seems to be going against a wrongly set provider. So when I connect with the wallet, all my calls get an error that 'the contract isn't deployed' because it is checking against a goerli-testnet provider rather than my devnet. I can set a default provider manually, but it gets overwritten when I access the wallet.


I am hoping that there is maybe a third wallet or something that can help me sidestep the concern. But perhaps my understanding of the situation is misguided. I am using starknet-react, if that maybe is contributing to the issue.

How do I develop against cairo devnet with browser wallets?

I'm new to Cairo and I want to know what is the difference when I write `let x = 1;` and `tempvar x = 1;`. Is there any difference in Cairo Lang between let and tempvar?

Cairo: let vs tempvar what is the difference?

What will the bundler ecosystem look like in AA?
