就像在Python中一样,如何在C中定义?

在python代码中,我们执行以下操作:


def(HI):

 print("<________________>\n")

 print("<________________>\n")

 print("HIHIHIHIHIHIHIHIHI\n")

HI()

它将打印出:

<________>
<________>
<________>
HIHIHIHIHI

How do we do it in a C code? i know there is a #define function, but i have only used it to define only one variable, like _ _ _ #define PI 3.142 . How do i do it?
