How do I use heterogeneous lookup with std::deque?

Heterogeneous lookup in C++ allows you to access elements in a container, like std::deque, using different types. This feature enables the flexibility of accessing the same container using different data types.

Learn how to use heterogeneous lookup with std::deque in C++. This tutorial provides an example illustrating the concept of accessing elements in a container using different types.
#include <iostream> #include <deque> int main() { std::deque myDeque; myDeque.push_back(10); myDeque.push_back(20); myDeque.push_back(30); // Heterogeneous lookup (not directly supported in std::deque) // Using std::variant or std::any for heterogeneous containers // Example: Accessing elements based on index for (std::size_t i = 0; i < myDeque.size(); ++i) { std::cout << "Element at index " << i << ": " << myDeque[i] << std::endl; } return 0; }
