I need to implement Dijikstra's and Floyds algorithm using a linked list !!! can anyone give a code on how to do it !! because i know to implement it using Matrix but am not familiar with the linked list !!

The rules of the implementation are:
1. weights are generated randomly not as input
2. All nodes are connected to each other
3. The code had to be implemented in C

below is the code I have been able to implement so far, but i need to implement Dijiktra nad Floyd in this.

#include <stdio.h>
#include <stdlib.h>

/*
*
*/
struct node{
int value;
struct node *nextNode;
};

int main(int argc, char** argv) {

int random[15*15-15];
struct node *pointerArray;
struct node *oneNode;
int i=0;
int j=0;
for(i=0;i<5;i++){
oneNode = (struct node *) malloc(sizeof (struct node));     // the first node of each row
oneNode->value = i;
*(pointerArray+i) = oneNode;
for(j=0;j<5;j++){
if(i!=j){
struct node *anotherNode = (struct node *) malloc(sizeof (struct node));     // the first node of each row
anotherNode->value = j;
oneNode->nextNode = anotherNode;
oneNode = anotherNode;
}
}
}
struct node *p;
for(i=0;i<5;i++){
p = *(pointerArray+i);
while(1){
printf("%d",p->value);
p = p->nextNode;
if(p!=NULL){
printf(" -> ");
}else{
break;
}
} //  end while
printf("\n");
}
return (EXIT_SUCCESS);
}
