Wow Subsonic, why couldn't it have been that easy for me lol but what I actually did was...

I gave the pointer a specifier. I didn't know a pointer needed one tho. And I now see the point of dereferencing. Still having trouble tho no matter what I do I get an infinite loop or just the last...

I don't know how to dereference so google here I come! But the way I was doing seesed right ya know! Point to the end of a string and reverse it till it reaches the begining and I see what you mean...

Here's the code:



int main(void)
{
Iint n;
Char *p;
Char *p2 = '\0';
Char array1[] = "Hey how are you?";

I have been trying to reverse a string with a pointer. I pointed to the end of a string literal:


P = array1 + strlen(array1) -1;

Then declare a 2nd pointer(p2) and set it to the beggining...

Prelude, I took out the write mode and used read. Because read returns a null character if the file doesn't exists. From there I can open a file with append mode. Or whatever. Thanks!!

Swarvy, I...

Swarvy.... I see what you are saying about the w+ mode and the append mode. I will drop the write and keep the append! I just thought I had to open a file for writing before I could append to it. So...

i am trying to figure out how to check if a file exists in my void existing_file(void) function, and if not i would like to create it. The big thing that i am trying to do is prompt the user for a...

Thank you CommonTater. And Adak, i didnt understand why it was used. so i asked!

i have googled and i have two books on C programming. that is why i am asking for insight and help, because i still do not understand. I try and learn on my own and if i need help i ask. that is what...

Still a tad bit confused, sorry! Why am i passing arguments to main anyway? If you may provide a more elaborate definition/explination. And may you give me a working example to run so i can see it...

I am learning how to pass arguments to main and it should not be hard to learn! But if someone could explain why it is used, what its for. i do not get the whole concept. The more/better i understand...

I am trying to learn File I/O but the way the book is "trying" to teach me is not quite sinking in!
Is there an easier way to code this?



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