If you type a program incorrectly and, say, omit a semicolon, the compiler gives you a syntax error message. Even if you type it correctly, however, the compiler may give you a warning similar to "Warning$-$conversion from 'double' to 'float,$\text{'}$ possible loss of data." An error message means you did something wrong and prevents the program from being compiled. A warning, however, means you've done something that is valid code but possibly is not what you meant to do$.$ A warning does not stop compilation.

Provide one example for error and one for warning.
