C++ Standard Template Library in Practice - Fill and Generate

The video tutorial introduces two STL functions: standard fill and standard generate. Standard fill is used to assign a single value to all elements in a range, while standard generate uses a generator callable to insert different values. The tutorial provides a C++ example using a functor to generate a Fibonacci sequence, demonstrating how to use these functions effectively. The video concludes with a preview of the next topic on numeric algorithms.

What is the primary limitation of using standard fill in C++?

• It cannot be used with iterators.

• It requires a generator callable.

• It can only fill arrays with zeros.

• It repeats the same value for all elements.

How does standard generate differ from standard fill?

• It can only be used with C++ vectors.

• It allows different values to be generated for each element.

• It requires two iterators and a value.

• It uses a fixed value for all elements.

What is a functor in the context of standard generate?

• A type of iterator used in C++.

• A struct or class that can maintain state between calls.

• A built-in C++ library function.

• A function that takes parameters and returns a value.

In the provided example, what sequence is generated using the Fib generator?

• Arithmetic sequence

• Prime number sequence

• Fibonacci sequence

• Geometric sequence

What is the purpose of modifying index 2 to equal 55 in the example?

• To test the limits of the array size.

• To show how to use standard copy.

• To initialize the array with a non-zero value.

• To demonstrate array modification after using standard fill.
