Hello, I need some help with this C++ task - Code provided below

First, look at the code by hand and try to identify vulnerabilities around memory and concurrency.

- Where is this code vulnerable to memory issues? What impact could that have on the results?

- Where is this code vulnerable to concurrency issues? What impact could that have on the results?

Now, run the code and try to exploit the vulnerabilities you identified above.

- What input are you able to enter into the program to cause a memory issue?

ADD YOUR SCREENSHOT OF THE OUTPUT SHOWING THE RESULTS FROM THE MEMORY VULNERABILITY:

- What input are you able to enter into the program to cause a concurrency issue?

ADD YOUR SCREENSHOT OF THE OUTPUT SHOWING THE RESULTS FROM THE CONCURRENCY ISSUE:

Improve the Code

Attempt to fix the issues you identified. Re-run the program and validate that you can no longer reproduce the memory and concurrency issues you found before.

- What did you correct in the code to address the issues?

#include  #include  #include  using namespace std; int balance = 100; void change_balance(int id){ usleep(id * 100); balance = id * 10; cout << " Thread " << id << " changed balance to " << balance << endl; } int main() { int size; cout << "Enter size: "; cin >> size; int* numbers = new int[size]; for (int i = 0; i < size; i++){ numbers[i] = (i+1) * 2; } for (int i = 0; i < size; i++){ cout << numbers[i] << " "; } const size_t thread_size = 5; thread threads[thread_size]; for (size_t i = 0; i < thread_size; i++){ threads[i] = std::thread(change_balance, i); } }
