get" title="Rendered by QuickLaTeX.com" height="20" width="61" style="vertical-align: -1px;">(array_name)

Parameters:

i – position of an element in the array, with 0 as the position of the first element.
arr_name – an array container.

Return Value:

Time complexity:

Program 1:

// 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 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
