Arrays in C++

Why is understanding data structures crucial for efficient programming?

In C++, what is the index of the first element in an array?

Which of the following is NOT a characteristic of arrays?

Given an array int arr[5], how would you access the third element in C++?

How can you determine the number of elements in a statically declared array in C++?

What happens if you try to insert an element into a full static array in C++?

What does function reusability primarily improve in programming?

Why is inserting an element at the end of an array typically faster than inserting at the beginning?

How does storing data in contiguous memory locations, as done in arrays, affect performance?

On what type of array is a binary search algorithm effective?

What is the primary purpose of defining functions in C++?

If a function in C++ is declared with a void return type, what does this indicate?

What distinguishes global variables from local variables in C++?

What happens when a function is called in a C++ program?

Given the following C++ code snippet, what is the size of the students array?

struct Student {
 string name;
 int marks;
};

int main() {
 const int SIZE = 3; // Number of students
 Student students[SIZE]; // Array of structures (3 students)

In the given C++ code example with the Student structure and the students array, how is the name of the first student accessed?

What is the purpose of the for loop in the provided C++ code snippet when handling the students array?

What data type is used to store the student's name in the Student structure in the provided C++ code?

If you wanted to add another field to the Student structure to store the student's grade point average (GPA), which data type would be most appropriate?

Given the Student struct contains name as a string and marks as an integer, how does C++ store this data in memory when an array of Student structs is created?

Suppose you want to implement a search function to find a student by name in the students array. Which search algorithm would be most efficient if the array is not sorted?

If the students array in the C++ example were dynamically allocated using new, how would you properly deallocate the memory to prevent memory leaks?

In the context of data structures, what is the significance of choosing the correct data structure for a particular application?

How does the concept of 'contiguous memory allocation' impact the use of arrays in scenarios where the size requirements are highly variable and unpredictable?

Considering function reusability, how does creating a function to search for a student by name improve code maintainability compared to writing the same search logic multiple times within a program?

If you are designing a system that requires frequent insertions and deletions at arbitrary positions within a sequence of elements, which data structure would be more suitable than an array?

Suppose you have an array of 1000 elements that is already sorted. Compare the time complexity of searching for an element using linear search versus binary search.

What is the primary advantage of using structures in C++, like the Student structure in the example, for organizing related data?

In the given C++ code example, if you wanted to create a function to update a student's marks, what parameters would the function likely require?

Considering the trade-offs between static arrays and dynamic arrays (e.g., using vectors in C++), when would using a static array be more appropriate?
