What is the output of the program
#include<stdio.h>
int main()
{
int a[5] = {2, 3};
printf("%d, %d, %d\n", a[2], a[3], a[4]);
return 0;

When we declare any array function, it will assign it s value start from a[0], a[1],...................
Eg:
int a[4]={1,2,3,4,5};
then
a[0]=1,a[1]=2, ........a[4]=5.
Eg:
int a[4]={1,2,3,4,5};
then
a[0]=1,a[1]=2, ........a[4]=5.

Every index value is Start is 0.
So, int a[5]={2,3}
a[0]={2}
a[1]={3}
a[2]={0}
Automatically initialized the value is called zero.
So answer is called 000.

What is an automatic array?

I think it should have garbage value. Right?

Give me an another example for this answer.

Ideally, it depends on the compiler to generate code to initialize a partially initialized array or not. Sometimes to save time it is not necessary to initialize it to zero.

C does not contain garbage collector so remaining elements will be garbage.
