Thread: gathering input as array

heyas, i am having some trouble with understanding how i can overcome a problem. Currently, i have a file named 'woop.txt' , stored in the c:\. The contents of the file is 'hello'. I wish to store this contents as an array, named 'word'. The following code is what i wrote to gather the file contents and print it on the screen, this code compiles successfully and has no problems.

int main()
{
FILE *fp;
int c;

fp = fopen("woop.txt", "r");
while((c = getc(fp)) !=EOF)
putchar(c);
fclose(fp);
getch();
}

Now, if i have:
char word[5];
definied, in order to store the contents of each letter in the array, i am required to have a for loop (could be wrong! :P)

I already have a while loop running, however, and if i have

while((c = getc(fp)) !=EOF)
fscanf("%c", &word[]);
it generates an error. my code for the initial output of the file works with 'c' storing the contents of each individual character, i want to store each one of those characters in word[].

the only experience i have with such storing would be to have a for loop as follows:
for(x=0;x<5;x++)
scanf("%c", word[x]);
this, mixed with my original code will create problems, however, due to the embeded loops of a while>for:
while((c = getc(fp)) !=EOF)
for(x=0;x<5;x++)
fscanf("%c", word[x]);
this code is obviously not going to work.

please give me any ideas or help
thanks in advance

This should work to write to the array but I don't have time to test it at the moment.

Code:

 
fp = fopen("woop.txt", "rb"); 
while((c = getc(fp)) != EOF)
word[i++] = c;
fclose(fp);

Notice that I changed your file permission (writes in UNIX) to read in binary mode. I recommend you do this as ASCII files tend to be self destructive. That shouldn't be a problem with a file this small though. Hope that helps, Good Luck.

could you please explain in more detail the line you added:

word[i++] = c;

theres the array of type char, and an integer i?
and your assigning the word[] arrray to c, then the 'i++' moves to the next value in that array, which would be word[1], then, again the value of c would be held and the 'i++' moves the word array to word[2].. and so on

is this correct? if so, could you please give me a little explination?
thanks a lot for your reply =)

Thanks Quzah. I wrote that reply to Twans question at about 3am .. Probably not a good idea lol. For some reason, I was just assuming that he was always going to run the program with a file of the same size. Thanks again for the correction.
