Example 1

void f(char );

int main()
{
  int n = 4;
  char c = 'h';

  f(c);
  return 0;
}

void f(char c)
{
  double x = 4.7;
  cout << c << endl;

  //*** point1 ***
}

Example 2

void f(char );

int main()
{
  int n = 4;

  f('h');
  return 0;
}

void f(char c)
{
  double x = 4.7;
  cout << c << endl;

  //*** point1 ***
}

Example 3

void f(char );

int main()
{
  int n = 4;
  int* A;
  A = new int[n]{1, 3, 5, 7};
  f('h');
  return 0;
}

void f(char c)
{
  double x = 4.7;
  cout << c << endl;

  //*** point1 ***
}

Example 4

void f(int* B);

int main()
{
  int n = 4;
  int* A;
  A = new int[n]{1, 3, 5, 7};
  f(A);
  return 0;
}

void f(int* B)
{
  B[1] = 0;
  //*** point1 ***
}

Example 5

void f(int* q);

int main()
{
  int n = 4;
  int* A;
  A = new int[n]{1, 3, 5, 7};
  int* p = &A[2];
  f(p);
  return 0;
}

void f(int* q)
{
  *q = 0;
  //*** point1 ***
}

Example 6

int* f();

int main()
{
  int* A;
  A = f();
  //*** control point 2 ***
  return 0;
}

int* f()
{
  int* B = new int[4] = {1, 3, 0, 7};
  //*** control point 1 *** 
  return B;
