The memory address of the first element of an array is called

  1. floor address

  2. foundation address

  3. first address

  4. base address


Correct Option: D
Explanation:

To solve this question, the user needs to have knowledge of arrays and computer memory.

The memory address of the first element of an array is called the base address. This is because the base address is the starting point or foundation of the array in memory. It is the address at which the first element of the array is stored.

Therefore, the correct answer is:

The Answer is: D. base address.

Option A is incorrect because floor address is not a term used to refer to the memory address of the first element of an array.

Option B is incorrect because foundation address is not a term used to refer to the memory address of the first element of an array.

Option C is incorrect because first address is not a term used to refer to the memory address of the first element of an array.

Which is the shallowest sea in the world?

  1. Caspian Sea

  2. Baltic Sea

  3. Superior Lake

  4. Arabian Sea


Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of sea depth.

Option A) Caspian Sea - This option is incorrect because the Caspian Sea is actually the largest enclosed body of water on Earth. It is classified as a lake rather than a sea. The Caspian Sea has an average depth of about 211 meters.

Option B) Baltic Sea - This option is correct. The Baltic Sea is the shallowest sea in the world. It is located in Northern Europe and has an average depth of about 52 meters. Due to its relatively shallow depth, the Baltic Sea is prone to freezing during winter.

Option C) Superior Lake - This option is incorrect because Lake Superior is not a sea but a freshwater lake located in North America. It is the largest of the Great Lakes and has a maximum depth of about 406 meters.

Option D) Arabian Sea - This option is incorrect because the Arabian Sea is an extension of the Indian Ocean and is known for its deep waters. It has an average depth of about 2,850 meters.

The correct answer is B) Baltic Sea. It is the shallowest sea in the world with an average depth of about 52 meters.
