How to use the make_tuple() function in C++

Harsh Jain

The make_tuple() function is available in the <tuple> header file in C++. This function is used to assign a tuplea finite ordered list of elements with values. The values passed should be in order with the values declared in the tuple.

Let’s understand with the help of an example.


To create a tuple that contains an integer, float, and character value, we need to execute the code snippet below:

tuple <int,float,char> ex;
ex = make_tuple(1,4.6,'d');

The result is that the data gets stored in the tuple according to the data types inside the tuple.

To create a dynamically typed tuple, the syntax is as shown below:

auto tup = make_tuple(1, 'a');

The statement above will create a tuple dynamicallywithout having to specify the data type and size beforehand .


There can be none or any number of parameters of the data types as specified when declaring the tuple in the function.

Return value

The function returns a tuple object of the appropriate data type of the arguments.


Let’s have a look at the code.

using namespace std;
int main()
  tuple <int, float, char> tup;

  tup = make_tuple(2,4.6, 'd');
  cout << "The values of tuple are : ";    
  cout << get<0>(tup) << ", " << get<1>(tup) << ", " << get<2>(tup) << endl;
  auto x = make_tuple(1, 'd');
  cout << "The values of dynamic tuple are : " << get<0>(x) << ", " << get<1>(x);

  return 0;    
Use the make_tuple() function in C++


  • In lines 1 and 2, we import the required header files.

  • In line 4, we make a main() function.

  • In line 6, we declare a tuple with int, float, and char data type parameters, in order.

  • In line 8, we use the make_tuple() function to assign the values of the same data type as the parameters of the tuple.

  • In line 10, we display a message about the result of the elements of the tuple.

  • In line 11, we use the get() method to access the values of the elements of the tuple and display them.

  • In line 12, we create a dynamicno need to specify the data type and size of the tuple beforehand tuple.

  • In line 13, we print the data present in our dynamically created tuple.

So, this is the way to use the make_tuple() function to assign values to elements of a tuple.
