C++ Developer - Built-In Arrays

The video tutorial covers arrays in C programming, explaining their syntax, indexing, and memory allocation. It discusses how to declare, initialize, and modify arrays, including the use of initialization lists. The tutorial also introduces range-based for loops, highlighting their advantages and how they prevent out-of-bounds errors.

What is a key characteristic of arrays in C?

• They can hold elements of different data types.

• They start indexing from 1.

• They are dynamically sized.

• They are stored in contiguous memory.

How is the size of an array specified in C?

• Automatically by the compiler.

• By the number of elements added.

• At runtime by user input.

• At compile time using a size declarator.

Which operator is used to access elements in an array?

• Dot operator

• Ampersand operator

• Subscript operator

• Arrow operator

What is the purpose of using symbolic constants for array size?

• To automatically initialize array elements.

• To improve code readability and maintainability.

• To allow dynamic resizing of arrays.

• To enable runtime size determination.

What is the starting index of an array in C?

• Depends on the array type

• It is user-defined

• 1

• 0

What happens if you try to access an array index out of bounds?

• The program will return a default value.

• The program will ignore the operation.

• The program will crash or return garbage data.

• The program will automatically resize the array.

What is an array initialization list?

• A list that specifies the size of the array.

• A list that allows dynamic resizing of the array.

• A list that initializes array elements with default values.

• A list that initializes array elements at the time of declaration.

What is a benefit of using a range-based for loop?

• It requires less memory.

• It prevents out-of-bounds errors.

• It allows dynamic resizing of arrays.

• It automatically sorts the array.

What does the 'auto' keyword do in a range-based for loop?

• It optimizes the loop for performance.

• It initializes the array with default values.

• It infers the data type of the elements.

• It automatically resizes the array.

In a range-based for loop, what does the loop variable represent?

• The memory address of the array.

• The element of the array.

• The size of the array.

• The index of the array.
