Question

I am trying to store a string data file into a multi-dimensional array using C.My sample data looks as below.I am thinking to use below char declaration for storing my data.Please kindly advise me if there is any other method.

char *array[6][10];

53,v42,p11,51097,310780,ok
56,v45,p11,260,1925,ok

I hope this sample program will help you to address your issue. I used structure and sscanf. This is the nice way to address this issue.

#include <stdio.h>
struct data
{
    char date[100];
    char state[100];
    char profit[100];
    char revenue[100];
};

int main()
{
      char line[4096] = {'\0'};
      char t1[100], t2[100], t3[100], t4[100];
      struct data d[2];
      int i = 0;
      while(fgets(line, 4096, stdin) != NULL) {
              sscanf(line, "%[^','],%[^','],%[^','],%s", &t1, &t2, &t3, &t4);
              strcpy(d[i].date, t1);
              strcpy(d[i].state, t2);
              strcpy(d[i].profit, t3);
             strcpy(d[i++].revenue, t4);
     }
     i = 0;
     while(i<2){
             printf("%s %s %s %s\n", d[i].date, d[i].state, d[i].profit, d[i].revenue);
             i++;
     }
 } 

$> a./exe < file

$> cat file
