Basically, the Standard Template Library provides templatized, general-purpose classes as well as methods. These classes and functions/methods implement several popular and most commonly used algorithms as well as data structures.
The environment in which your code runs is imperfect: users will provide invalid inputs, external systems will go down, and your code and other code around it will often contain some number of bugs. Given this, errors are inevitable; things can and will go wrong, and as a result you can’t write robust and reliable code without thinking carefully about error cases.
