need help reading text into a 2D Array

[oilerscrazy]

I am stuck, I need to read text from a txt file line by line into a 2d array. I need suggestions

Check this code snippet...

FILE *fp;
int rows=0, idx;
char f_content[10][80]; 
//This array will hold the contents.
//ASSUMING a line in the text file wont exceed 79 chars.

if(!(fp=fopen("TextFile.txt","r")))
	{
	printf("\n\tError opening file...");
	exit(0);
	}

while(!feof(fp) && rows<10)
	fgets(f_content[rows++],80,fp);

fclose(fp);

printf(&quot;\n\tContent read from the file are...\n&quot;);

for(idx=0; idx<rows;idx++)
	printf(&quot;\nROW%d:%s&quot;,idx,f_content[idx]);

printf(&quot;\n=================End of Data==================\n&quot;);

have fun coding... ;-)

why not just use a pointer to an array of strings?

char *strings[];  // An array of strings
int iStrings = 0;

// Using fgetc()

while ( (c = fgetc(file)) != EOF) {
  sprintf(strings[iStrings] + len(strings[iStrings]), c);
  if (c == '\n')
    iStrings++;
}

Be advised...This is NOT the best way to do this, I made it to be as simple as possible. If you will be processing larger files, This routine would be a bit slow...Plus I'm at work, so gimmie a break

Good luck, Rob

A better way...

#define MAX_LINE_LENGTH  100  // Set this to something      
                              // reasonable

char *strings[];  // An array of strings
int iStrings = 0;

// Using fgets()

while(!feof(file)) {
  fgets(strings[iStrings], MAX_LINE_LENGTH, fp);
  iStrings++;
}
