# Create account

Since there are no Externally Owned Accounts (EOA) in StarkNet, all Accounts in StarkNet are contracts.

Unlike in Ethereum where a wallet is created with a public and private key pair, StarkNet Accounts are the only way to sign transactions and messages and verify signatures. Therefore an Account - Contract interface is needed.

Account contracts on StarkNet cannot be deployed without paying a fee. Creating an account is a bit tricky; you have several steps :

1. Decide on your account type (OpenZeppelin, Argent, ...).
2. Compute the address of your future account.
3. Send funds to this pre-computed address. The funds will be used to pay for the account contract deployment, and remains will fund the new account.
4. Actual deployment of the Account

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! This is day 17 of the 17 days of the Cairo Challenge. In this challenge I want to ask you [install](https://www.cairo-lang.org/docs/quickstart.html) Cairo and try to launch your first program. What have you implemented as your first Cairo language program?

**Step 1**
```solidity
// 1. Make sure that you installed dev packages on your device
sudo apt install -y libgmp3-dev // Linux
brew install gmp // Mac OS
```
**Step 2**
```solidity
// 2. Install Cairo using Python virtual environment
python3.9 -m venv ~/cairo_venv
source ~/cairo_venv/bin/activate
pip3 install ecdsa fastecdsa sympy;
pip3 install cairo-lang;
```
**Step 3**
```bash
// 3. Make sure you have python 3.9. Because Cairo was tested with python3.9. To make it work with python3.6, you will have to install contextvars:
pip3 install contextvars
```
**Step 4**
```python
// 4. Write your program
// Create a file, named hello.cairo, with the following lines:
 
func main() {
		// edit me: you can add here any output, best program wins the challenge
    ret;
}

```solidity
//5. Compile your program
cairo-compile hello.cairo --output hello_compiled.json
```
**Last step**
```solidity

//6. Run:
cairo-run \
  --program=hello_compiled.json --print_output \
  --print_info --relocate_prints

//7. Debug:
//You can open the Cairo tracer by providing the --tracer flag to cairo-run. Then open it at http://localhost:8100/.
```
