Question

"int a[10];

int* ptr;What does ptr = a + 5 equal?
a) ptr = &a[5]
b) ptr = &a[4]
c) ptr = a[5]
d) ptr = a + 5"

Answer 1

In C programming, 'ptr = a + 5' sets the pointer to the address of the 6th element of the array 'a', which is the same as '&a[5]'.

Step-by-step explanation:

The statement ptr = a + 5 in C programming means that ptr is set to point to the memory address of the 6th element in the array a, because array indexing starts at 0. Therefore, ptr is equivalent to &a[5], which is the address of the 5th index in the array (which is the 6th element).
