C++ Points code example

Example 1: pointer in c++

int* pointVar, var;
var = 5;

// assign address of var to pointVar
pointVar = &var;

// access value pointed by pointVar
cout << *pointVar << endl;   // Output: 5

In the above code, the address of var is assigned to the pointVar pointer.
We have used the *pointVar to get the value stored in that address.

Example 2: dereference pointer c++

value = *pointer // Use * to dereference the pointer
