In your previous thread you've already been suggested to use code tags, perhaps you missed it?

I'm very sorry that my eyes aren't good enough to see the error messages on your computer's monitor.
Do you maybe expect that...

Plenty of questions, plenty of weak programmers, or both ?

Only that proves to me that you didn't get what they describe in that link :)

Well, I'm not sure what he's trying to do (as he didn't provide an illustrating example).
I think he wants to convert a 'readable' string to a string...

>string ss="this is an encrytpion program";
Could it be that you meant: char ss[] = "this is an encrytpion program"; here?
Otherwise please clarify.

Can you also post all the errors you're having?

>I am having a hard time writing a program to do the following.........
Please tell us where you're having problems with.

system() doesn't return the output of an executed command.
It returns an integer value, which indicates whether it could execute the command successfully or not....

I didn't say that, can you quote me the sentence?

I guess you didn't understand me, let's analyze it:
If you write i=i++;,...

Edit:: Don't bother reading this.

Writing i=i++; is essentially the same as writing:

i=i;
i++;
and because it's the same variable here it's essentially the same as writing:
i++;

getchar() will only get one character, which means that when you enter a character and press the ENTER button on your keyboard, the ENTER is not read (which means it stays in the input stream,...

Too lazy to just split them up like this?

It's better to return a fixed value when your program has exited successfully because in your current program, the return value...

Dream2Code,

Sure you didn't mean:
a=strstr(b,"name");
instead of:
a=strste(b,"name");
?

I assume this was a typo because probably the r-key comes just after the e-key on your keyboard.

1) read only
2) writeable

3) wrong, you only create a pointer of type char, this can't hold a string.
BTW, if you had written it like this:

/* wrong */
char abc[5];
abc = "xyz";

Sorry I misunderstood you.

Using standard C: no.
Using the OS's API: yes.

No, let's revise: your pointer points to a string constant (remember it's a constant = read-only), up until here there's nothing wrong, but further in your program there's an instruction which tries...

Possible, but if your main function contains your whole program, then I would rather suggest you to use: return exit_code; instead of the exit() function :)

Why would you want to wrap this if around the while:

if (k > 1 && m < n)
{
while(k > 1 && m < n)
{

}
}

A little addition on:

Yes, an array name is a constant pointer to the first element of that array.

Depends on the way how you implement it, if you each time decrease with 3, then you only have to check whether it's higher or equal to 3.

Well, I would be glad if you had read my post:

:)

You don't understand what I'm saying, right?

Why starting with 30 if you can easily start with 3 and each time add 3 ?
Then the output will be in a more logical order, right?

Step 1: Get an integer from the user (store it in a variable)
Step 2: Check whether the integer is higher or lower than zero:


IF number < zero:
Print out the multiples (Step 3)


Step 3...

return (void*) y;
What do you do here?
You create a pointer and put the value of y in it, this means that you let the pointer point to memory address 10 (not to the value 10 !!) in your example,...

It's not recommended to just program it like that because you return a pointer to a local (automatic) variable, and when the function returns, the variable will be 'destroyed' (this means: it doesn't...
