Doubt in a concept

#1

Sir, I had a confusion.
when i intialise like int* a=new int[5]{0}, all elements are initialized to 0 but when I initialse like int* a= new int[5]{2}, all the elements do not get initialised to 2

#2

yes
this concept is not only limited to dynamic memory allocation

also valid on any type of array initialization

int arr[5]={1,2};

first two elements will be 1 and 2 rest are 0

int arr[5]={0};
all element are initialized with 0

int *a =new int [5]{}

inside braces you have to pass the initial value of array if don’t pass it assume them to 0
