unknown amount of threads cpp

1. Define the number of threads required for the program.

2. Create a function that will be executed by each thread. This function should contain the code that needs to be executed concurrently.

3. Initialize a thread object for each thread you want to create. The number of threads should be equal to the value defined in step 1.

4. Start each thread by calling the start method on the thread object.

5. Wait for all the threads to finish executing by calling the join method on each thread object.

6. Optionally, retrieve the results of each thread's execution if necessary.

7. Clean up any resources used by the threads, such as releasing memory or closing files.

8. End the program.

Note: Each step should be accompanied by the necessary code snippets or explanations to illustrate the process.
