cout << *pa <«

Expert Solution

Step 1

Here we take three-pointer types variables pa, pb, and pc which are pointing at the memory locations a, b, and c respectively. Now the value at pa is 15 , at pb = 12 and at pc = 5.

Now, pb = pc so, value at pb = 5.

Now pa = pb so value at pa is also equals to 5. So, pa = pb = pc = 5.

Now, we are printing *pa which the value at the address pa i.e. 5, and similarly with pb and pc.

So, we get the output 5,5,5.
