How can we properly declare multiple pointers?

• int *myPtr1, *myPtr2;

• You cant, must be one at at time

• int* myPtr;

  int *myPtr2

• int* myPointer,myPointer2

What will be the output?

int y=9;   

int yPtr;   

yPtr = &y; 

      cout<<" y = " << y <<endl;   

cout<<" &y = "<< &y  <<" \n ";   

cout<<"yPtr = "<< yPtr <<" \n ";   

cout<< "yPtr = "<<*yPtr<<" \n ";
