Simple Pointer Example Program In C++

Definition

The pointer is a one of the C++ programming language data-type whose value refers directly to (or “points to”) another value stored elsewhere in the computer memory using its address.

Pointer Variable Assign Syntax:

pointer_vaibale = &variable; 

C++ Example Pointer Program:

#include<iostream> 
#include<conio.h> 

using namespace std;

int main() {
    int i = 10;
    int *Ptr;

    Ptr = &i;
    cout << "\nValue Of i :" << i;
    cout << "\nAddress Of i :" << i;
    cout << "\nValue Of Ptr :" << Ptr;
    cout << "\nAddress Of Ptr :" << &Ptr;
    cout << "\nPtr's Pointer Value:" << *Ptr;
    cout << "\nPtr Equal to &i :" << *(&i);
}

Sample Output

Value Of i :10
Address Of i :10
Value Of Ptr :0x6dfefc
Address Of Ptr :0x6dfef8
Ptr's Pointer Value:10
Ptr Equal to &i :10

(Output may vary based on system and its memory)

How It Works

This C++ program demonstrates Simple Pointer. It first prepares the data it needs, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
