Program Plan Intro

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.

Given Program:

//Include libraries

#include <iostream>

//Use namespace

using namespace std;

//Define main method

int main()

{

// Declare array

int a[10];

// Declare variable

int *p = a;

// Declare variable

int i;

//Loop executes until the value of i exceeds 10

for (i = 0; i < 10; i++)

//Assign value i to a[i]

a[i] = i;

//Loop executes until the value of i exceeds 10

for (i = 0; i < 10; i++)

//Display value

cout << p[i] << " ";

cout << endl;

//Pause console window

system("pause");

//Return 0 value

return 0;
