Let's say I have a small authenticate(Client client) method in some class. The authentication could fail for a number of reasons...

Also, if the method that might fail is "low languages.

Suppose you are using the ternary operator, or the null coalescing operator, or nested if-else statements to choose assignment to an object. Now suppose that within the conditional statement, you have the evaluation of an expensive or volatile operation...

For situations where the is OK ) ? temp : null;
Ok, so one could have a method

Error code is:
bool isOK(int code) { return code == SQLErrorCode.OK; }
and your code could become:
if (isOk(getErrorCode())) { callFunction2; } else { callFunction1; }
Not that it matters much.

I've programmed C and C++ for a long time and so far I've never used exceptions and try / catch. What are the benefits of using that instead of just having functions return error codes?
