read file into array

I have a text file contains the following:
apple meaning of apple
degree meaning of degree
How would I read each line and put them into array of char?
I have the folloing but need some advice on how to do it, please.

Code:

---

#include<stdio.h>
#include<stdlib.h>
#define MAXLINE 10
void main(void)
{
        char* readline[MAXLINE];
        FILE *infile;
        char* line;
        int ch;

        if((infile = fopen("info.txt", "r"))==NULL )
        {
                fprintf(stderr, "Error: Cannot open input file. ");
                exit(1);
        }

        line = (char *)malloc(sizeof(char));

        while(fscanf(infile, "%s", line) != EOF)
        {
                printf("%s\n", line);

                while (ch = fgetc(infile) != '\n')
                {
                        advice.....
                }

        }
}

fgets is your friend.

Quzah.

void main... in case you didn't see this in my reply to your other post :)

>line = (char *)malloc(sizeof(char));
you don't need the cast of the malloc return, loose it!
>line = malloc(sizeof(char));
Hey wait a min..... your malloc'ing one byte of memory, you aren't going to store much in there!
If you wanting a temp buffer to store data in as you read it, use something like
>char line[100]; /* or whatever length */

And yes, as Quzah said, drop fscanf() and fgetc(), and use fgets(). Once you have the complete line into one array, you can then think about splitting the line up by words if so you wish.

>void main(void)
No, int main ( void )

>fprintf(stderr, "Error: Cannot open input file. ");
perror would work better here.

>exit(1);
An exit condition of 1 is non-standard, use either 0, EXIT_SUCCESS, or EXIT_FAILURE. The latter two are in stdlib.h.

>line = (char *)malloc(sizeof(char));
In C you don't need the cast and often it can hurt more than help. You are also only trying to allocate one byte, this is probably not what you want.

>while(fscanf(infile, "%s", line) != EOF)
This gives you one word at a time, not one line. For a complete line, fgets would be the better function to use.

My recommendation is to declare line as a static array with a size large enough to hold the length of the lines. Each time you read a new line, allocate space for that string in the next empty space of readline. Copy the string from line to readline with strcpy, increment a counter for readline and do it again:

Code:

---

while(fgets(line, sizeof line, infile) != NULL && i < MAXLINE)
{
  printf("%s\n", line);
  readline[i] = malloc(strlen(line)+1);
  if(readline[i] != NULL)
    strcpy(readline[i++], line);
}

I have array of string which have the following:
one meaning of one
two meaning of two
three meaning of three

For example, "one" is a word and "meaning of one" is a meaning of one. How would I divide each line into two pieces so I can have word and meaning separately?

I would like to use getline but don't know how to use it.
I want to use a first space to separate those into word and meaning.
Please let me know. thanks

This is what I have and it works... now how do i divide the each line into two separate pieces...
for example, char *array[i] = "apple meaning of apple"
I want to divide "apple" and "meaning of apple" separately.
Can I use getline? How do i use it?

Code:

---

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#define MAXCHAR 30
#define MAXLINE 10

int main(void)
{
        char *line[MAXLINE];
        char templine[MAXCHAR];
        FILE *infile;
        int i=0, count=0, len, ch;

        if((infile = fopen("info.txt", "r"))==NULL )
        {
                perror("Cannot open input file");
                return EXIT_FAILURE;
 
        }

        while(fgets(templine, sizeof templine, infile) != NULL)
        {

                line[i] = malloc(strlen(templine)+1);
                len = strlen(line[i]);
       
                if (line[i] != NULL)
                        strcpy(line[i++], templine);

                count++;
        }
       

        for (i=0; i<count; i++)
                printf("line %d has: %s", i, line[i]);
        printf("\n");

        fclose(infile);

        return EXIT_SUCCESS;
}

I've answered this same question twice already, so I'm not going to do it again. If you want my answers, check back in the other threads you posted this.
