Explanation of Solution
Pointer in C++:
A pointer is a variable whose value will be another variable’s address. Generally, a pointer variable is declared as follows:
type *var-name;
Here, type is the pointer’s base type and var-name is the pointer variable name. The asterisk is used to designate a variable as a pointer.
Example Program:
//Include libraries
#include <iostream>
//Use namespace
using namespace std;
//Define main method
int main()
{
// Declare variable
int n = 10;
// Declare pointer variable
int *in;
// Store address of var in pointer variable
in = &n;
//Print the value of the variable
cout << ...
