本文深入探讨了异常处理和断言在编程中的应用，阐述了它们在应对非由错误代码引发但可能改变控制流程的外部不可预测事件时的重要性。通过实例说明了如何在代码中合理使用try...catch结构来捕捉异常情况，并利用断言检查代码逻辑的正确性。文章强调了根据不同情况和语言选择适当策略的必要性。

Try... catch - for exceptional conditions, i.e. conditions which aren't caused by malformed code, but which may just alter the normal control flow by external unpredictable events.

Assertions for catching invalid code, i.e. checking if an invariant is held in the function, checking if an internal method is called with right arguments (for public API you might still want an exception for that), etc.

Those are my basic guidelines, but the conventions vary from situation to situation and from language to language.
