Vector of Tuples in C++
To create a vector of tuples, we will have to first declare a vector of type tuple. It means that each element of the vector will be a tuple. Moreover, we also have to specify the type of tuple.
Syntax
vector<tuple<type1, type2, ...>> myVector.
We can simply use the std::make_tuple() method to insert the data into the vector.
For traversing, we can use the tuple::get() method to iterate over the elements of the tuple present in the vector.
C++ Program to Create a Vector of Tuples
C++
// C++ program to create a vector of tuples #include <iostream> #include <vector> #include <tuple> using namespace std; int main() { // Intialize a vector of tuples vector<tuple< int , char , float >> vecOfTuples; // Add tuples to the vector vecOfTuples.push_back(make_tuple(10, 'A' , 3.14)); vecOfTuples.push_back(make_tuple(20, 'B' , 6.28)); vecOfTuples.push_back(make_tuple(30, 'C' , 9.42)); vecOfTuples.push_back(make_tuple(40, 'D' , 10.8)); // Iterate over the vector and print each tuple int i=1; cout<< "Vector Elements:" <<endl; for ( const auto & tuple : vecOfTuples) { // Access tuple elements using get<index>(tuple) cout << "Tuple " <<i<< ": " << get<0>(tuple) << ", " << get<1>(tuple) << ", " << get<2>(tuple) << endl; i++; } return 0; } |
Output
Vector Elements: Tuple 1: 10, A, 3.14 Tuple 2: 20, B, 6.28 Tuple 3: 30, C, 9.42 Tuple 4: 40, D, 10.8
Time Complexity: O(N) where N is the number of tuples inside the vector
Auxiliary Space: O(N)
How to Create a Vector of Tuples in C++?
In C++, a tuple is an object that allows the users to store elements of various data types together while a vector is used to store elements of the same data types. In this article, we will learn how we can create a vector of tuples in C++.
Example:
Input:
Tuple1 ={10,A,5.3} Tuple2= {20,B,6.5}
Output:
Vector Elements:
Tuple 1: 10, A, 5.3
Tuple 2: 20, B, 6.5
