What is the meant by char* p= new char[0]; ?

Question

I recently saw a code with a char pointer was initialised like
char *str= new char[0];
But I can't understand why it is possible and what is its use?? Please help

Answer 1

this is a pointerto a character and 0 marks the end of a string. this is an array of strings which are terminated by the value null, its memory adress pointer is marked with null.

Answer 2

Declared a string pointer variable *str and initialized it with char[0] element.

Answer 3

Nur MD Bijoy (Rohan) according to your answer a pointer is initialised by a char!!
[0] is the size of array here

Answer 4

Buhle so now str ==nullptr ?
Or (*str) == '\0'?

Answer 5
