Question

#include< iostream>
using namespace std;
int main() {
int A[4] {0,1,5};
cout<<A[3] ;
cout<<A[4] ;
cout<<A;
return 0;

}

find following without WAP
1>>cout<<A[3] ;
2>>cout<<A[4];
3>>//Output of
cout<<A;

Explain ur answer

Answer 1

arr[4] causes array index out of bound error, results in undefined behaviour, in your case - Garbage values, which is whatever was left behind in the memory block.

An array of size 4 has index 0, 1, 2 and 3 only.

Answer 9

rest arr[3] =0 as it has been allocated a blank space for array but has not been assigned so default is 0.

Answer 10

And cout<<A; gives memory address of A[0] u may verify by cout<<&A[0];
