# Error C2065 Example 2: undeclared identifier

Description:

An undeclared identifier error, error C2065, implies that there is no declaration for the particular item. However, this example shows that this error can be caused by mistyping a '1' (the number one) instead of an 'l' (lowercase L) in the word 'endl'. This is a very common mistake and is sometimes hard to see because of the visual similarity of the characters.
