array get() function in C++ STL Last Updated : 29 Aug, 2018 Comments Improve Suggest changes Like Article Like Report The array::get() is a built-in function in C++ STL which returns a reference to the i-th element of the array container. Syntax: get< i >(array_name) Parameters: The function accepts two mandatory parameters which are described below. i - position of an element in the array, with 0 as the position of the first element. arr_name - an array container. Return Value: The function returns a reference to the element at the specified position in the array Time complexity: O(1) Below programs illustrate the above function: Program 1: CPP // CPP program to demonstrate the // array::get() function #include <bits/stdc++.h> using namespace std; int main() { // array initialisation array<int, 3> arr = { 10, 20, 30 }; // function call cout << "arr[0] = " << get<0>(arr) << "\n"; cout << "arr[1] = " << get<1>(arr) << "\n"; cout << "arr[2] = " << get<2>(arr) << "\n"; return 0; } Output: arr[0] = 10 arr[1] = 20 arr[2] = 30 Program 2: CPP // CPP program to demonstrate the // array::get() function #include <bits/stdc++.h> using namespace std; int main() { // array initialisation array<char, 3> arr = { 'a', 'b', 'c' }; // function call cout << "arr[0] = " << get<0>(arr) << "\n"; cout << "arr[1] = " << get<1>(arr) << "\n"; cout << "arr[2] = " << get<2>(arr) << "\n"; return 0; } Output: arr[0] = a arr[1] = b arr[2] = c Comment More infoAdvertise with us Next Article array data() in C++ STL with Examples pawan_asipu Follow Improve Article Tags : Misc C++ STL cpp-array CPP-Functions +1 More Practice Tags : CPPMiscSTL Similar Reads STD::array in C++ The array is a collection of homogeneous objects and this array container is defined for constant size arrays or (static size).
