2 dimension array of characters
 

Hi , I am stuck with two dimension array of characters.

for example, I have 4 lines in a file( lines should be treated as arrays of string) called source:

i am not good at C.
i hope improve soon.
i need help.
it is very cold.

I want read the first two lines and store them in a 2-dimension array of characters called destination.

I know how to read (all the lines but not the first two) but when I tried to input the line in destination I get errors: I tried strcpy, memcpy...

What can I do please?

does not give what I want!!

What's wrong with using your count? Just count to two, don't look for the remainder unless you have some other objective.

Be very careful using eof as a loop exit at the top of the loop. Behavior can vary depending upon whether or not the last line in the file ends with a newline. Either way you decide to go can screw up performance if the other condition occurs. You'll wind up losing the last line or using it twice. I recommend making a "while (1)" loop and exiting explicitly when you detect EOF or error. Refer to your 'fgets' documentation very carefully.

Like DaWei said, just count to two. Here's what you can do.
[php]#include <stdio.h>
#include <string.h>

uhOh(char * error)
{
fprintf(stderr, "%s\n", error);
return 1;
}

main()
{
FILE * fin;
int i, count = 2;
char source[256];
char destination[2][256];

if((fin = fopen("source.txt", "rb")) == NULL)
{
return uhOh("Cannot open file");
}

for(i = 0; i < count; i++)
{
if(fgets(source, 100, fin) == NULL)
{
if(ferror(fin))
return uhOh("An error has occured, check it with ferror()");
if(feof(fin))
{
printf("done\n");
return 0;
}
}
else
{
strcpy(destination[i],source);
printf("LINE: %s\n", destination[i]);
}
}
fclose(fin);
}[/php]

You don't get to printing "done" because the for loop ends, but try filling in count = 5 instead.

ROFL, Ruben! You KNOW that I have the uhOh function and close relatives copyrighted!!!111!!eleven!

Haha, I always see you using it, so I thought I'd learn from the pro's. :D

@brad sue: The uhOh function with courtesy of DaWei.

[php]
return uhOh("An error has occured, check it with ferror()");[/php]
should be:
[php]
return uhOh("Trouble in River City.");
[/php]
:D

Infogeek,
Thank you very much
I am writing a standard C code, not php, but I think the logic is the same..
I will try it now.
Thank you

The 'PHP' tags don't necessarily indicate PHP code, bradsue, they cause syntax highlighting to occur whereas the ordinary 'code' tags don't. InfoGeek is teasing me because I often name the string in the function prototype as he has shown :D .

OOHH!
I am sorry ( I know so littlle!!)
