First, use NASM to compile an ASM file in ELF format. The Assembly file contains global _ start and functionc, which will be used for future connection. Extern is used to represent functions in the external C language.

Call structure of my program: _ start (ASM)-> funb (c)-> func (ASM)
Among them, the ASM files include extern funb, global _ start, and global func.
C file Declaration: void func ();
