Predict the output or error(s) for the following


Predict the output or error(s) for the following

#include
main()
{
int a[2][2][2] = { {10,2,3,4}, {5,6,7,8} };
int *p,*q;
p=&a[2][2][2];
*q=***a;
printf("%d----%d",*p,*q);
}
Answer:



SomeGarbageValue---1
Explanation:
p=&a[2][2][2] you declare only two 2D arrays, but you are trying to access the third
2D(which you are not declared) it will print garbage values. *q=***a starting address
of a is assigned integer pointer. Now q is pointing to starting address of a. If you
print *q, it will print first element of 3D array.
