An assertion (assertion) is a statement in Java that contains a Boolean expression that, when the Boolean value is True, the program is considered correct, and when the Boolean value is False, the system throws an error.Assertions are disabled by default and can be turned on at development time, helping to correct errors and increase maintainability.PS: Assertion

Type assertion is the value of the interface type that is loaded into the (x) type (T) . The format is:
x.(T)v:=x.(T)v,ok:=x.(T)

A simple record of the usage scenarios for type assertions (types assertion) are normally developed.1. Parameters used to convert interface{} types in a functionAll types in Golang implement an empty interface interface{}, so it is usually used as an abstract type parameter of a function. To give a simple chestnut:

This problem was encountered when debugging a multi-target tracking program in vs2008. The problem was ignored in the next release. In the release version, you do not need to worry about this problem, that is, the system helped you block it, but the
Reading a line of input into a string does not need to consider how much space is given as an array, which makes acm more convenient.
C ++ 98 has two functions that can read a row into a string, as shown below:

How do these parameters interact, basically, two principles are followed: specific settings take precedence over general settings, and subsequent settings take precedence over the previous settings.
