c++ tuple push_back

#include <iostream>
#include <tuple>
#include <vector>

int main() {
    std::vector<std::tuple<int, double>> vec;

    // Creating a tuple
    std::tuple<int, double> myTuple = std::make_tuple(10, 3.14);

    // Pushing the tuple into the vector
    vec.push_back(myTuple);

    return 0;
}

1. Include Libraries: Import necessary libraries (iostream, tuple, vector) for input/output, tuples, and vectors.

2. Main Function: Define the main function where the program execution begins.

3. Vector Declaration: Create a vector named vec that stores tuples holding an integer and a double (std::tuple<int, double>).

4. Tuple Creation: Create a tuple named myTuple initialized with values 10 (integer) and 3.14 (double) using std::make_tuple.

5. Pushing into Vector: Use vec.push_back(myTuple) to add the myTuple tuple into the vec vector. This appends myTuple to the end of the vector.
