Example
In the following example, we declared a Tuple with three elements of type int, string and boolean respectively.
tuple<int, string, bool> fruit;
In the following program, we declared two tuples: fruit and person, with different set of element types.
C++ Program
#include <iostream> #include<tuple> using namespace std; int main() { tuple<int, string, bool> fruit; tuple<int, string> person; fruit = make_tuple(2, "apple", true); person = make_tuple(55, "Budha"); }
Conclusion
In this C++ Tutorial, we learned how to declare a Tuple using tuple keyword, in C++, with examples.
