CPP

C++ using a member function of a class to pass parameters to a thread

class myFunc
{
public:
  void function()(int* arr1, int length)
  {
    cout << "Array length: " << length << "...passed to thread1." << endl;
    
    for (int i = 0; i != length; ++i)
    {
      cout << arr1[i] << " " << endl;
    }
  }
  
  void negativeSign(int* arr1, int length)
  {
    cout << "Array length: " << length << "...passed to thread1." << endl;

    for (int i = 0; i != length; ++i)
    {
      cout << arr1[i] << " ";
    }

    cout << "Make negative all elements/integers of array." << endl;

    for (int i = 0; i != length; ++i)
    {
      arr1[i] *= -1;

      cout << arr1[i] << " ";
    }
  }
};
