Title: C Everything

INFO

• This is a C repository containing a curated set of data structures and algorithm.website
• The data structures are implemented keeping them Generic and Abstract.
• Genericness: Since in C any data structure is completely type dependent, we've tried to achieve a genric data structure that supports any standard data types (int, char, float, etc..) and user defined data types (struct user {})
  • The means by which we achieved a data structure by storing the pointer to the data (std or user defined) rather the data itself
  • Given below is a snippet of code explaining the same,

// Link list node definition
typdef void* t_gen;                     //< Generic data pointer

typedef struct llnode {
        t_gen data;                     //< Pointer to the data to be stored in link list
        struct llnode *nxt;             //< Pointer to next node in list
        struct llnode *prv;             //< Pointer to prev node in list
} t_llnode;

• Abstractness: The operations/procedures for each data structure is abstracted to the user by using function pointers, thus creating a psuedo class like structure

t_linklist *l;
t_dparams dp;

// Data type specific operations to be given to data structure
init_data_params(&dp, eSTRING);

// Create a string XOR link list
l = create_link_list("STRING XORLL",eXOR_LINKLIST, &dp);


// Add elements to linklist
l->add(l, "Hello");
l->add(l, "World");

// print linklist
l->print(l);

// Destroy linklist
l->destroy(l);
