Maybe this question is not related to C language at all, maybe is. I wonder why in excel number of columns is 255 and maximum number of characters for naming file is 255. Is there any connection?
...

I have these codes:




#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
int main()
{

I don't understand why you use sizeof as argument, and why in this line if (i < (n - 1)) you need n-1?

Thanks.

Thanks guys for your help.

I compiled program that andyhunter helped me with, and it functions good. It counts characters. I am confused with variable n. Do I really need it? str represents array...

I am trying to read characters and count its numbers. First, my compiler prompted me for the size of the array. I added number 50, why do I have to specify size in this case?

I understand that fgets is the best for user input, comparing with scanf and gets. What is going on with the output? Is puts safe to use, and how much data this function can handle? If you use fputs...

I followed Hammer's tutorial on Comparing Strings, but one thing I don't understand.

Hello!

I am taking steps now to learn C thoroughly since you encouraged me to do so. Thanks. Now I have some questions for you. I see in most of the programs that main has no any arguments or...

Thanks for your optimism. This was the question that was maybe unnecessary. So, you can be C programmer, have a job, make the applications. That's great, I am going to start learning this language...

Hello!

I would like to make me a program about shopping expences. The best idea in C is to use structures for that. Correct me if I am wrong.

I did this little code here:

I think that problem should be in this line:

There is call to function getline along with its parameters, this function is not declared. You should...

I just want to point on this part of codes written by kinghajj char continue = 'y';

continue is reserved keyword, so is it allowed for naming variables? I know so far that it is not allowed....

Hello!

This is the code:




#include <stdio.h>
#include <stdlib.h>
#include <string.h>

I have this piece of code:




if(!feof (fp))
{
insert(&startPtr, item.part, recoff);
recoff = ftell(fp);
fread(&item, sizeof(struct invent), 1, fp);

Thanks Kip this was wonderful explanation.

I have another code:




newPtr = (LISTNODEPTR) malloc (sizeof(LISTNODE));

I have this code:




void insert(LISTNODEPTR *, char *, long );
void delete (LISTNODEPTR *, char *);
int isEmpty(LISTNODEPTR);
void printList (LISTNODEPTR);

Thanks quzah!

I have another error message. I assume it is something about the brackets. This is whole complete code again.

Hello!

Can somebody tell me is name tag for structures required? I tried to find the answer in my C book but i found nothing.

Thanks.

Hi quzah!

I forgot to tell you how I fixed this problem. I put tag name inside and I think it works fine now. My compiler doesn't point at that spot anymore.

This is what I did:
