I think in this exercise they want you to know about if .. else statement. Try this:


```
func abs_eq(x: felt, y: felt) -> (bit: felt) {
    if (x==y) {
        return (bit=1);
    }
    if (x == -y) {
        return (bit=1);
    } else {
        return (bit=0);
    }
}
```


Hi, I'm trying to solve a Playground exercise on the [Cairo website](https://www.cairo-lang.org/playground/) named "Conditionals". I don't know how to make OR operator in Cairo. I tried something like that:

```
func abs_eq(x: felt, y: felt) -> (bit: felt) {
    if (x == -y) or (x == y) {
        return (bit=1);
    } else {
        return (bit=0);
    }
}
```

but it gives me an error


`Error: code:12:18: Unexpected token Token('IDENTIFIER', 'or'). Expected: "{".
    if (x == -y) or (x == y) {`

How can I solve it?

Hello, I deployed my contract using Argent X.
I click on "Developer settings" and then "Smart contract developement". I declare and deploy the contract.
Also used [this guide](https://www.newton.so/view/63a1890e581919f84b2a4c51) and it helped me.

But the contract is not automatically verified on starkscan or voyager. What should I do to get verified?

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?

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.

i get thrown this error when deploying with v0.3.3

Will alpha-goerli not be supported in future updates?

Hello! This is day 3 of the 17 days of the Cairo Challenge. And I have no idea how to solve the [playground](https://www.cairo-lang.org/playground/) exercise “Conditionals”. Perhaps you can help me?

```python
// The function `abs_eq` should return 1 if its inputs
// are equal or differ only in sign and 0 otherwise.
// Its current implementation is incorrect.
//
// 1. Click on "Run" to see where it fails.
// 2. Fix the body of `abs_eq`, so that the
//    program terminates successfully.

// Returns 1 if |x| = |y| (that is, x = y or x = -y),
// 0 otherwise.
func abs_eq(x: felt, y: felt) -> (bit: felt) {
    if (x == -y) {
        return (bit=1);
    } else {
        return (bit=0);
    }
}

func main() {
    let (bit) = abs_eq(2, -2);
    assert bit = 1;

    let (bit) = abs_eq(2, 3);
    assert bit = 0;

    let (bit) = abs_eq(2, 2);
    assert bit = 1;

    return ();
}
```
