Question
What will be the output of the following C++ code?int arr[] = {1, 2, 3, 4, 5};cout << arr[2];1234
Solution
The output of the given C++ code will be '3'.
Here's the step by step explanation:
-
An integer array 'arr' is declared and initialized with 5 elements {1, 2, 3, 4, 5}.
-
The 'cout' statement is used to print the element at the 2nd index of the array.
-
In C++, array indexing starts from 0. So, arr[0] is 1, arr[1] is 2, and arr[2] is 3.
-
Therefore, 'cout << arr[2];' will print '3' to the console.
The numbers 1234 at the end of your question seem to be misplaced as they don't contribute to the code or the output.
