可视代码片段关系图也支持代码组的条件执行，可以通过添加条件控制结构来创建。

A visual snippet diagram also supports the conditional execution of code groups, which you create by adding a conditional control structure.

这个控制结构是由一系列具体限制条件组成的一个“if”语句。

This control structure is an 'if' statement represented by a concrete list of plain Erlang terms.

选择结构化活动(也称为切换)根据条件控制流程采用的路径。

A choice structured activity (also known as a switch) controls which path the process takes, based on a condition.

There are so many other constructs like loops and conditions and such, so what I thought we do in conclusion today is look at this program.

这里有很多其他结构类型如循环控制,条件分支等等，所以我觉得应该,以这个程序作为结束。
