Printing pointer to pointer to a string

I'm not 100% sure if what I'm writing is the problem or if the problem is elsewhere. I am given this '**string;' which, of course points to a string. I need to print this string. I'm simply doing printf("%s",str ing) and every combination with '*' thereof but not getting the expected string to print (either garbage or a fault). What am I forgetting?

Hmm. Might be something else is the problem. I looked at the assembly language and what I originally tried seems to be working:
printf("%s",**s tring);

The function that is giving me **string is declared as
'char** getstring(void) ;'
and I am doing this:
Expand|Select|Wrap|Line Numbers
  1. char** string;
  2. char** getstring(void);
  3.  
  4. string=getstring();
  5. printf("%s",**string);
  6.

Nope. So I'm back to my original question. Am I forgetting something?

Nope. A char* might point to a C string. char * array like char *string[] could also be expressed as char**. You have an array of strings on hand. Might want to take a closer look at the code that is involved.

Can we all say "Arrrrghhh! "

In my print routine, I wasn't checking for when there was no string. The way it would fail made me think it was problems with my pointer scheme.

I am having a problem with printing selected pages. Actually, the problem isn't with printing selected pages as it is more to do with having blank pages print for those pages that have not been selected. For example, if I were to have 5 pages with every second page printing, I would get the following results: Page 1 = Print OK Page 2 = Blank Page 3 = Print OK Page 4 = Blank

I'm trying to write a program like hexel. I guess I could fish out the source for hexel and look at that, but for now I'm trying to figure out how I can do with with std::stringstream and std::string. I had something working with std::string. I simply treated it as an STL container, and iterated over its elements. The results were a bit confusing to me. Some of the stuff was printing out as 1 or 2 characters hex numbers, as I...

Consider an implementation that doesn't use all bits 0 to represent a NULL pointer. Let the NULL pointer is represented by 0x12345678. On such an implementation, if the value of NULL pointer is printed will it be all 0's or 0x12345678 int main(void) { char *ptr; ptr = 0;

I have a small VB program that has a printing module...very simple....and works great. However, If I try to print to a generic printer, I get the following error: "The data area passed to a system call is too small". I found the following article, that I assume is similar to my problem, which is of little help: http://support.microsoft.com/default.aspx?scid=kb;en-us;822779 Any suggestions?

I am converting an old application that was printing directly to a specialized printer device (i.e. a special label printer). It was doing this by opening a file with the file path of 'LPT1:' and then using PRINT # to print directly to the printer device. Obviously, this is not going to work under VB.NET - StreamWriter won't let you open a device like LPT1: and such. I assume I am going to have to switch to the System.Drawing.Printing...

Hello all! I'm at my wits end trying to search for what I assumed to be a relatively straightforward task.

At first I thought it was a simple matter to have the button's "onclick" attribute set to "window.print();". However, that always brings up the print dialog box. ...

Hi, To print the pointer using printf(), we convert it to (void *) . printf("%p",(void *)ptr); My question is how printf() determine which type of pointer is passed to it and prints its value accordingly ? I have this doubt as different pointers may have different representation and different size. So, how does printf determine

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
