C++: Lecture 1: Pointer's in C++ : Mastering C++ Made Simple !

 Mastering Pointer's Made Simple: Your Easy Guide to C++ !

Pointer's in C++ code [C++] :

#include<iostream>

using namespace std;

void increment(int &num){

    num++;

    cout<<"Value of number inside the function: "<<num<<endl;

}

int main()

{

    int a = 5;

    int b = 7;

    increment(a);

    increment(b);

    cout<<"value of a outside function : "<<a<<endl;

    cout<<"value of b outside function : "<<b<<endl;

    int *ptr = &a;

    int *ptr2 = &b;

    int **p2p = &ptr;

    cout<<"a = "<<a<<endl;

    cout<<"b = "<<b<<endl;

    cout<<"Ptr = "<<ptr<<endl;

    cout<<"Ptr2 = "<<ptr2<<endl;

    cout<<"p2p = "<<p2p<<endl;

    cout<<"Value of address stored at ptr = "<<*ptr<<endl;

    cout<<"Value of address stored at ptr2 = "<<*ptr2<<endl;

    cout<<"Value of address stored at p2p = "<<**p2p<<endl;

    return 0;

}
