The variable name, c, doesn't need to be quoted.

变量名c不需要加引号。

So as Ryan proposed, I could change my variable's name to just A for short.

所以正如Ryan所建议的，我可以将变量的名称改为A。

This is the same syntax, but I'm using a different variable name.

这是相同的语法，但我使用不同的变量名。

In this case, the statement says a variable named A has the number 5 stored in it.

在本例中，语句表示名为 A 的变量中存储了数字 5。

It'd be annoying to copy and paste this everywhere, and have to update the variable names each time.

将其复制并粘贴到各处会很烦人，而且每次都必须更新变量名称。

The rest of our code is the same as before, now tucked into our function and with new variable names.

我们的其余代码与以前相同，现在隐藏在我们的函数中并具有新的变量名称。

Also, instead of using specific variable names, like " relays" and " levels" , we specify generic variable names, like Base and Exp, whose initial values are going to be " passed" into our function from some other part of the program.

此外，我们没有使用特定的变量名， 如“relays” 和“levels”，而是指定通用变量名， 如 Base 和 Exp， 它们的初始值将从程序的其他部分“传递” 到我们的函数中。
