My file contains a series of numbers (integer, float, integer, float ....), each written on a separate line. The numbers of columns are different from one line to another i.e.

1 2.45 3 1.75

5 3.45 7 2.55 9 3.25

6 1.75 4 3.55 6 2.55 9 2.45

The program should read the contents of the entire file and place the data into an array of type float with an entry for each line. Here is my basic solution, but this is only suitable if I have fixed no of columns.

float Read(FILE *pFile)
{
 char line[50]; char letter[5];
 fi = fopen("file.txt", "r");

 while (fgets(line,200,fi)!=NULL)
 {

    sscanf(line,"%f %f %f",&a[i], &a2[i],&a3[i]);
     printf("%2.0f %2.5f %2.0f\n",a[i],a2[i],a3[i]);
}

fclose(fi);
return a[i];
}

Please HELP.
