Dynamic string array using string, what's the problem?

Question

C++ / C#

#include <iostream>
#include <string>
using namespace std;

int i = 2;
string *a = new string[i];

int main()
{
  a[0] = "abc";
  a[1] = "del";
    i++;
    a[2] = "monday";
    cin.get(); cin.get();
  delete [] a;
  return 0;
};

Answer 1

Honestly, the problem is your stupidity.
To get started, read the book. Everything is simple and easy there. Many questions will disappear by themselves.
PS By changing the variable i you will not change the size of the array s.

Answer 2

i++;
    a[2] = "monday";

Out of bounds array. An array of length 2 has two elements: [0] and [1].
