my code is

 #include<iostream>

 using namespace std;

 int main()
{
int size;

cout << "enter number of letters in your name\t:";

cin >> size;

char *array = new char[size];

cin.getline( array, size);

for (int i = 0; i <= size; i++)

    cout <<'\n'<< array[i];

delete[] array;

cin.get();
}

and my output is some weird thing

enter number of letters in your name    :5

and after this execution stops, for loop is newer executed.

I know i am using old styled string but we have to use this as recommended by our high school

`for (int i = 0; i <= size; i++)` is wrong. It should be `for (int i = 0; i < size; i++)` because `array[size]` is out of bounds. Valid indices are from 0 to size-1 – drescherjm May 24 '16 at 13:04

What did you mean to do by `cin.getline(array, size)`? – Khalil Khalaf May 24 '16 at 13:06
@drescherjm still you get weird symbols – ramsay May 24 '16 at 13:07
Related: http://stackoverflow.com/a/21567292/3410396 . Although it talks about C++ strings, underlying cause and solution is exactly the same. – Revolver_Ocelot May 24 '16 at 13:07
if your name is of `size` letters, you should allocate at least `size+1` chars in `array` – max66 May 24 '16 at 13:08
@Revolver_Ocelot Hm, I wonder if I should close the dupe I closed with to be a dupe of that one. – Barry May 24 '16 at 13:08
@Barry even after adding that `cin.ignore()` i get same symbols – ramsay May 24 '16 at 13:11
@ramsay How you did that? Where did you put it? What is your code? – Revolver_Ocelot May 24 '16 at 14:02
