Create counter contract

[danielcdz]

Description

• One of the famous examples of a simple contract is a counter contract, which allows users to increment, decrement, or reset a counter value stored on the blockchain. It is a foundational example of understanding how to write, deploy, and interact with smart contracts.

Steps

• Add a new simple counter contract in the corresponding directory.

Hi @danielcdz kindly assign me i just finished cairo boot camp and have some experience writing smart contracts using cairo and i believe this task would help me solidify my understanding. Kindly assign me if avaliable

steps to solve the above task:

1. I need to implement the following:

   • A storage variable to hold my counter value
   • Public functions to manipulate this value
   • Events to track changes

2. I'll need these main functions: a) Constructor:

   • Initialize my counter to 0
   • Set up any initial state

b) get_counter():

• Let me read current counter value

c) increment():

• Add 1 to current value

d) decrement():

• Subtract 1 from current value

e) reset():

• Set counter back to 0

  3. I'll emit events for:
     • Counter incremented (new value)
     • Counter decremented (new value)
     • Counter reset

4. I'll test:
   • Initial value is 0
   • Increment works
   • Decrement works
   • Reset works
   • Multiple operations work correctly

i would like to take this issue @danielcdz

i am a new contributor to repo and would like to start my contribution journey with stark-cairo-nodes

would solve this issue by creating a storage field counter and 3 functions (increment, decrement and reset)

Thank you

Could I be assigned to this?

I’d like to help with this.

Can I take this issue?

I will start by creating a simple counter contract in the specified directory that stores a counter value and provides methods to increment, decrement, and reset the counter. Then i will Include a get_counter function to retrieve the current counter value, ensuring the contract is straightforward and well-documented.

I'd be happy to do this.

hi , im fron dojo coding

steps

1- declare mi smart contract counter

2 - declare my 3 functions (increment, decrement, reset)

3- deply tha contract and testing if works well

thank you

I’d like to resolve this.

i have experience in writing and testing smart contracts

[MullerTheScientist]

hello please can i address this issue

[wheval]

Can I take care of this issue? I have built this contract before, and would love to contribute to this repo. I would also write test for the contract and ensure they pass. Please assign. ETA is 1 day. Thank you.
