See lines 2 and 3 of output. In the program pn is assigned to pm. What Is The Problem With Pointers Quickadviser The pointers pn and pm are of type int and are initialized with values n and m respectively while px py and pch are initialized by values x y and ch respectively. . Here type is the pointers base type. Consider the following example for better understanding. Here we will print the size of different types of pointer variables. A void pointer is a pointer that has no associated data type with it. Both returns pointer which means irrespective of what elem is in your code the expression ptrelem will always be a pointer which you can use to invoke the member functions as shown above. Since ptrelem is pointer which means checking it for nullptr be good idea. Pointers can be used with array and string to access elements more efficiently. Int ptr NULL. Here is a sample code of casting structure pointers...
