pushing values to a pointer of vector cpp code example

Example 1: c++ iterate over vector of pointers

for (vector<int Type>:: iter = myVector.begin(); iter != myVector.end(); iter++)
   (*iter)->display();

Example 2: pointers to pointers in cpp

#include <iostream>
 
using namespace std;
 
int main () {
   int  var;
   int  *ptr;
   int  **pptr;

   var = 3000;

   // take the address of var
   ptr = &var;

   // take the address of ptr using address of operator &
   pptr = &ptr;

   // take the value using pptr
   cout << "Value of var :" << var << endl;
   cout << "Value available at *ptr :" << *ptr << endl;
   cout << "Value available at **pptr :" << **pptr << endl;

   return 0;
}
