I currently have an array with 8TB, that will eventually grow to 10TB+ with 2TB disks. How would I partition, format, then mount an array of this size, and also have room to grow, when I add new disks? I heard ext3 only supports 8tb? So would lvm be the best use here?
View 2 Replies View RelatedThe first is about implementing function calls. The way I currently have it is that functions are called with a C++ std::vector of nodes as the parameters. How would I turn a comma-seperated list of expressions into a C++ vector in the grammar?Second, how do you implement left-associative operators in a parser that does not allow left recursion?
And third, what would be the best internal representation of integers? A C++ int seems simplest, but limited. Using GMP seems more versatile, but I'm afraid it might seriously slow down the interpreter compared to C++ ints.
I wonder why arrays in the C programming language are pointers to the first element of the array, not the first element of the array itself?

On a vinyl cutter to have the blade pivot it must be offset from the center of the shaft it's on so say for example a .25mm offset would leave a .25mm unwanted vinyl attachment when the cutting is done. I somehow have to average or extrapolate that .25mm xy coordinate and add it to the hpgl plot file as a PUx,y; command? I have enclosed a simple sample file that has three images in it. In the corresponding hpgl file everything between the PU commands that are starting with PD are the code for that image (star for eg the pu to move to next image and then all PD for the next image and so on, so once the formula or procedure is figured out it can be applied to as many images there are in the file. Placing the new command at the head of each image PD group. Since there are absolute and relative cutters I enclosed the same exact plot for both types as the coordinates on relative can be negative numbers. Only PU and PD commands and a ";" as a command delimiter as sometimes many commands are on one line.The offset variable will come from a spinbox but .25 is good for an example.

I'm making script for automated compiling of one program which would output builds optimized for many architectures. For clearancy, I do each build in it's own catalogue and list of builds with their respective catalogues would be stored as array. I'm using this guide as reference. It describes making array as naming a variable with additional brackets denoting it's position in array.
In my code, it looks exactly like this:
Code:
mtune[1]="build/mtune/athlon"
mtune[2]="build/mtune/athlon-4"
mtune[3]="build/mtune/athlon-mp"
[code]....
But upon invoking $mtune or any $mtune[x] variable, output is blank, like the variable(s) were never initialized. What am I doing wrong?

I'm trying to figure out how to code for this specific type of instance - I want to use a hash and have the key be a reference to an array, and not use the key in the standard way of it being a scalar. Basically, I have a large output that I need to process line by line, and rather have access to it as an array than a big block in a scalar. For the big block hash as a scalar I would do -
Code:
foreach $CONTROLLER (<CONTROLLER_LIST>) {
$ALL_DISKS{$CONTROLLER} = `ssh -n <commands>`;
}
Now I know I could take the scalar and split it to another array after the fact like -
Code:
@TEMP_HOLD = split (/s+/,$ALL_DISKS{$CONTROLLER});
How would I code it that I would have access to the key information as an array and not a scalar? I know it needs to be a pointer and we're going to have -> in there somewhere, but not sure how to approach it. Some of the documentaiton I've been reading about referencing I've found a little confusing so far, and trying to figure out how to use them in context of what I'm working on.
I'm writing a code to get the index of the last occurrence of a given substring in a string.
Code:
int StringHandler::lastIndexOf(string src, const string s) {
unsigned int lastIndex = string::npos;
if (src.find(s, 0) == string::npos) {
return -1; } else {
bool isLast = false; unsigned int i = 0; do {
lastIndex = src.find(s, i);
if (lastIndex != string::npos) { i = lastIndex + 1;
if (i == src.size()) { isLast = true;
} } else { isLast = true;
} } while (!isLast);
} return lastIndex;
}
My problem is: execution steps into an if with a false condition! Check the values of i and src.size() at the right panel. How could be possible for the program to run the highlighted statement? The if condition above is false! [URL]. I could use char arrays, for example, but this kind of false validation has happened to me more than once, I'm using G++ 4.5 with these flags: -O0 -g -Wall -c
I just started programming in PHP so I haven't figured out how to do this yet, but I have a multi-dimensional array that I need to sort by one column. That's fine...but I need the sort to ignore case! Right now I have it sorted by 'name' (the other column is 'uid').
The problem is that by the default the sort is case-sensitive so the array looks like this:
Code:
Apple 4015
Banana 4011
Cherry 4045
avocado 4046
I want to be able to sort the the 'name' column in a case-insensitive manner so that the array actually looks like:
Code:
Apple 4015
avocado 4046
Banana 4011
Cherry 4045
How to accomplish this? Just FYI I'm not actually sorting the PLUs for fruits...but it was a simple example. I'm actually doing this for a Facebook application.
I would like to combine two arrays and delete duplicates that might occur. I tried to solve it like this:
Code:
combined=( "${results1[@]}" "${results2[@]}" )
printf "${combined[@]}" | sort -n | uniq
Example:
result1 (4 elements):

In my code printf seems to have a problem with elements that have the same letters but a space inbetween. For instance "new foo", "newfoo" are the same for printf
I've got a situation. I'm having GNU bash version 3.00.16(1) on Solaris 10. I need to declare an array say arr1 which will be populated by an output of a command.
declare -a arr1
arr1=( $(/some/command) )
Supposing it will eventually (after executing the command) have element values as -
arr1[0]=1234
arr1[1]=5678
arr1[2]=7890
Now, I need to declare another set of arrays, one for each of the element values above - e.g.
declare -a arr1_1234
declare -a arr1_5678
declare -a arr1_7890
And I also need to populate elements of each of above 3 arrays with output of another command in a loop. So, these arrays will hold values something like -
arr1_1234[0]="abc"
arr1_1234[1]="def"
arr1_1234[2]="ghi"
arr1_5678[0]="jkl"
arr1_5678[1]="mno"
arr1_5678[2]="pqr"
arr1_7890[0]="tuv"
arr1_7890[1]="xyz"
arr1_7890[2]="aab"
I'm able to declare and populate arr1[*]. My question is how do I declare, populate and print the subsequent arrays and their elements?I am feeling rather thick to get this working.
I am curious if there is a way to describe and use variable sized multi-dimensional arrays in C using pointers. I mean, for 1-dimensional array e.g. I can use the following piece of code:
...
int i , N;
int *array;
scanf("%d", &N);
array = (int*) malloc(N*sizeof(int));
for (i=0; i<N; ++i) array[i] = i; // Assigning values to the array
for (i=0; i<N; ++i) printf("%d ", array[i]); // Printing the assigned values
free (array);
...
But what about the two dimensional array[N][M] ? I guess I have to use a double pointer e.g: int **array. But how exactly? Note that I use C90 and not C99.
I have a problem with arrays in awk. What i want is to take some data from a file (ssh log) and print it to a html table. I have managed to print some stuff (user logged in and how many times they have logged in) What i want more is to take all the ip that each user logged in from and print it in a row next to the username and times (in the code i typed blabbla where i want the ip to be shown. How do you think i should approch that, multidimensional arrys maybe?

I've been told to move my code from MFC to linux platform, and so I did, trying to keep as much as I can on the way, now, I had a dll and application, the application I rewrote all anew while the dll I only made changes so it'll be an ".so" file, now, when I try to link using "dlopen", I get the message "undefined symbol: _ZN5ImageC1EiiPh", now, Image is a class in the DLL, which even makes its own ".o" file for the DLL itself. I just can't understand why it happens. I use Image in functions which are not in Extern "C", but the functions I want to use don't use it. Also, I have many globals in the DLL, (because that's how the DLL was written in the past) but none of them is Image...
Is the problem with the fact I include a c++ class in the DLL? How can I solve such a problem? I tried messing with how I link it, but I think that's not the issue here.
I use g++ and -rdynamic --export-dynamic -ldl -lrt for the application
and for the dll I use -shared -Wl,-soname, and -lm, and for the .o files of the dll -Wall -fPIC (although for some reason it doesn't let me do it through the makefile and I needed to do that by hand, which was a little weird. I put it in tag, I put it in line, but it still did nothing...
