What will be the output of the following C++ code? #include <iostr...


Explanation:

There are a few key points to understand about the given code:

- The code declares three integer variables a, b, and c with values 5, 10, and 15 respectively.
- An array of integer pointers arr is declared and initialized with the addresses of variables a, b, and c.
- When the statement `cout < arr[1];`="" is="" executed,="" it="" will="" output="" the="" address="" of="" the="" second="" element="" in="" the="" arr="" array,="" which="" is="" the="" address="" of="" variable="" />
- However, when you try to output the address using `cout`, it will not display the actual address value but will instead display some random number. This is because the address is being treated as an integer value and not as a memory address.

Therefore, the output of the code will be some random number and not the value of variable b.

Correct answer: d) it will return some random number
