Question

Can you use the random_shuffle template function with a list container?

Short answer

Answer: No, we cannot use the random_shuffle function directly with a list container as it requires random access iterators, which list containers do not support. However, we can achieve the same randomness effect by using the shuffle function provided in the C++11 standard library.

Step-by-step solution

Understand the Problem

The random_shuffle template function is used to randomly shuffle the elements within a sequence container such as vectors and lists. The goal is to determine if random_shuffle can be used with a list container.

Include the Necessary Libraries

To use random_shuffle and lists, include the following libraries in your code: ```cpp #include #include ```

Create a List Container and Populate It

Create a list container of integers and add some elements to it. ```cpp std::list myList {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; ```

Use Random_Shuffle with List Container

Unfortunately, the random_shuffle function cannot be directly used with list containers, as it requires random access iterators, which list containers do not support. However, we can achieve the same effect with the shuffle function provided in the C++11 standard library. This function works with any iterator type that satisfies the requirements of a suitable UniformRandomBitGenerator. First, we need to include the respective headers and create an instance of the random number generator: ```cpp #include #include std::random_device rd; std::mt19937 g(rd()); ``` Now we can use the shuffle function to shuffle the elements in the myList container: ```cpp std::shuffle(myList.begin(), myList.end(), g); ``` After executing this code snippet, myList elements will be randomly shuffled.
