Destructuring assignment in C++

Unfortunately, C++ does not have a built-in feature for destructuring assignment like some other programming languages such as JavaScript and Python. However, you can achieve a similar effect with the help of std::tuple, a standard C++ library container that can hold a collection of values of different types.

Here is an example of how to use std::tuple to achieve destructuring assignment in C++:

``c++
#include
#include

int main() {
std::tuple my_tuple {1, "hello", 3.14};

int my_int;
std::string my_string;
double my_double;

// Destructuring assignment using std::tie
std::tie(my_int, my_string, my_double) = my_tuple;

std::cout << "my_int: " << my_int << std::endl; // Output: my_int: 1
std::cout << "my_string: " << my_string << std::endl; // Output: my_string: hello
std::cout << "my_double: " << my_double << std::endl; // Output: my_double: 3.14

return 0;
}
`

Here, we create a std::tuple providing it with three values of different types. We then declare three variables of types, int, std::string, and double. We then use std::tie, a standard C++ library function, to assign the values from our my_tuple` to our three variables in one line of code.

Thus, we achieved something similar to destructuring assignment in other programming languages.
