To look up a value, we do the usual array-indexing magic. For all the others, although all pointers are essentially memory locations they are still typed, and the compiler will warn about assigning one type of pointer to another. 1) Pointer reduces the code and improves the performance, it is used to retrieving strings, trees, etc. and used with arrays, structures, and functions. Here is the simple program for printing the character using Pointer and Arrays in C++. Here, ptr is the name of the variable, which is of type Integer . Also, note that an asterisk is used as a prefix before the variable name. Asterisk is mandatory to add as a prefix to the variable name, if we don’t add then it will not be treated as a pointer variable.
