Urgent
can anyone give me a pratical example where unions can be used to
avoid C++ type checking ?

I don't know if that could be done quickly but I can show you how a Union causes multiple variables to point to the same address.

void pause()
{
    std::cin.sync();
    char c = getchar();
    std::cin.sync();
}

union dont_do_this {
    int a;
    char b;
};

int main(int argc, char *argv[])
{
  dont_do_this A;
          A.a = 1;

  int B = 1;
  char C = (int) B; //Same As Type Casting
  
  std::cout << A.b << '\n' << C;
  
  pause();
  return 0;
}

Do you have a specific thing you are trying to work around? I could help you with a more direct question.
