c++ dynamic array implementation code example
Example 1: linkedlist implementation in c++
#include <iostream>
using namespace std;
struct node
{
int data;
node *next;
};
class linked_list
{
private:
node *head,*tail;
public:
linked_list()
{
head = NULL;
tail = NULL;
}
void add_node(int n)
{
node *tmp = new node;
tmp->data = n;
tmp->next = NULL;
if(head == NULL)
{
head = tmp;
tail = tmp;
}
else
{
tail->next = tmp;
tail = tail->next;
}
}
};
int main()
{
linked_list a;
a.add_node(1);
a.add_node(2);
return 0;
}
Example 2: how to create dynamic string array in java
List<String> zoom = new ArrayList<>();
zoom.add("String 1");
zoom.add("String 2");
for (String z : zoom) {
System.err.println(z);
}
