sparse matrix and linked lists

  Asked By: Won Wook    Date: Jun 13    Category: C Programming    Views: 3222

Hey guys,

I'm trying to make a function that reads a sparse matrix off a textfile and makes a linked list of that matrix

I want it to use <stdio.h> and a node should be in a style like

struct node {
int row;
int col;
int elem;
struct node *down;
struct node *right;

Reading off a text file would be like

int linkedlist(void) {
int i, j, row, col, val;

FILE *file = fopen("matrixA.txt", "r");
fscanf(file, "%d", &row);
fscanf(file, "%d", &col);

for(i=0; i<row; ++i) {
for(j=0; j<col; ++j) {
fscanf(file, "%d", &val);

and then putting whatever value into the linked list.

I'm struggling to make this function, and to figure out the starting address of this list.

Please help!
