modular

I'm trying to build a huge Modular Web App with AngularJs and RequireJS. This is my directory that I want to build: |--index.html |--css |--images |--libs | └--angular.js | └--angular-route.js | └--require.js | |--js | └--app.js | └--controller.js | └--module |--user | |--controller | | └--index.js (that is controller to list all users) | | └--add.js (this controller to add new user) | |--service | | └--user.js | └--template | └--index.tpl.html | └--add.tpl.html | └--photo |--controller | └--index.js | └--add.js |--service | └--photo.js └--template └--index.tpl.html └--add.tpl.html In app.js

For my upcoming university C project, I'm requested to have modular code as C allows it. Basically, I'll have .c file and a corresponding .h file for some data structure, like a linked list, binary tree, hash table, whatever... Using a linked list as an example, I have this: typedef struct sLinkedList { int value; struct sLinkedList *next; } List; But this forces value to be of type int and the user using this linked list library would be forced to directly change the source code of the library. I want to avoid that, I want to avoid the need to change the library, to make the code as modular
