How implicit dynamic linking works in C? How to call a library function located in .SO or .DLL?

Implicit Dynamic Linking:
Let us consider once again math.c file for dynamic linking. We want to make it as a dynamic library. First we compile it with position independent flag on(-fPIC). This is needed for dynamic/static linking.
$cc -fPIC -c math.c

Now make a shared library with the object file.
$cc -shared libmath.so math.o

To use this shared library in a application we need to do the following steps:

1. compile the application code (place math.h in include folder)
   $cc -c app.c -Iinclude -o app.o
2. Link with import library math.lib
   $ld app.o -lmath -o app
3. Copy the libmath.so in lib path or current path and run the application
   $./app
