This section describes how to design and pass Multiple Parameter subfunctions. In Section 2.3, we discussed how to design a sub-function with parameters. Now we will study how to transmit the design methods of two or more parameters. Why do functions require parameters? In fact, the reason is very simple, that is, to give more data to the sub-function for processing. It seems too stretched to pass only one parameter to the sub-function, similar to C, Python
