❓️ Question 20: #CPP
The length of an array in C++ is significant because it determines ____.

1. the number of elements that can be stored in the array

2. the memory allocated for the array

3. the maximum size of the array

4. All of the above

✅ Correct Response: 1

Explanation: The length of an array in C++ is significant because it determines the number of elements that can be stored in the array. It affects the memory allocation for the array and defines the maximum size of the array. Understanding the length of an array is important for proper memory management, accessing array elements, and avoiding potential issues such as accessing out-of-bounds indices.

❓ Question 21: #CPP
To access elements in a structure in C++, you use the structure variable name followed by ___.

1. A dot operator (.)

2. An arrow operator (->)

3. A hash sign (#)

4. A dollar sign ($)

✅ Correct Response: 1

Explanation: In C++, to access elements in a structure, you use the structure variable name followed by a dot operator (.) and the name of the structure member. For example, if you have a structure 'Person' with a member 'name', you can access it using 'person.name', assuming 'person' is an instance of the 'Person' structure. The dot operator is used to access individual members of the structure.
