What does this means ? Console.writeline("index out of bounds"); means?

Question

What is this line or coding saying?

Answer 1

"Index out of bounds" as an error would typically indicate that you've gone beyond the limits of an array.
For instance;
int arr[10]; // create an int array with 10 elements
....
....
Console.Write(arr[10]); // produces an error. There is no index 10 in this array. Arrays are zero based so an array with 10 elements would have indices that range from 0-9, not 10.

Answer 2

that line simply outputs the string parameter to console. when you run that code, you will view that string in the command prompt. like this:

index out of bounds
