How do I construct and use std::tuple in C++?

In C++, `std::tuple` is a fixed-size collection of heterogeneous values. This allows you to group different types together, making it easier to pass around complex data structures. Here's how you can construct and use a tuple in C++.

Constructing and Using std::tuple

To construct a tuple, you can use the `std::make_tuple` function or the tuple constructor directly. You can access the elements using `std::get` with the appropriate index.

#include #include int main() { // Creating a tuple auto myTuple = std::make_tuple(1, "Hello", 3.14); // Accessing elements int intValue = std::get<0>(myTuple); const char* stringValue = std::get<1>(myTuple); double doubleValue = std::get<2>(myTuple); // Printing values std::cout << "Integer: " << intValue << std::endl; std::cout << "String: " << stringValue << std::endl; std::cout << "Double: " << doubleValue << std::endl; return 0; }
