A pointer is a special kind of variable in C and C++ that
holds the address of another variable.


my first pointer
#include <iostream>
using namespace std;

int main ()
{
int firstvalue, secondvalue;
int * mypointer;

mypointer = &firstvalue;
*mypointer = 10;
mypointer = &secondvalue;
*mypointer = 20;
cout << "firstvalue is " << firstvalue << endl;
cout << "secondvalue is " << secondvalue << endl;
return 0;
}



firstvalue is 10
secondvalue is 20
