Pointer in c++

Address in C++

To understand pointers, you should first know how data is stored on the computer.

Each variable you create in your program is assigned a location in the computer's memory. The value the variable stores is actually stored in the location assigned.

To know where the data is stored, C++ has an & operator. The & (reference) operator gives you the address occupied by a variable.

If var is a variable then, &var gives the address of that variable.

Example 1: Address in C++

#include <iostream>
using namespace std;

int main()
{
    int var1 = 3;
    int var2 = 24
    int var3 = 17;
    cout << &var1 << endl;
    cout << &var2 << endl;
    cout << &var3 << endl;
}

Output

0x7fff5fbff8ac
0x7fff5fbff8a8
0x7fff5fbff8a4C++ Inheritance
