Is it possible for a function to return two values?
Array is possible if the two values are both the same type, but how you return two different type values?
Thank you very much.
fprintf(stderr,"Error in pcap_findalldevs: %s\n", errbuf);
I don't want to output anything via fprintf,but only the result of "Error in pcap_findalldevs: %s\n", errbuf,what's the function for that?
I was playing around with recursion and did this simple function. I was assuming that it would print out 9-0 to stdout, but, it prints 0-9. I can't see how that happens at all.
int main()
{
rec(10);
return 0;
}
int rec(int n){
if(n > 0)
printf("%d\n", rec(n -1));
return n;
}
it lets this function declaration
print(int size,int table[size][size]){
int i,j;
printf("-------TABLE-------\n");
for(i = 0;i
gives error in this situation
44 C:\Users.. previous implicit declaration of 'print' was here
(print(size,table); call in main)
void print(int size,int table[size][size]){
int i,j;
printf("-------TABLE-------\n");
for(i = 0;i

How do these filters affect the output of imagepng() in PHP?
PNG_NO_FILTER
PNG_FILTER_NONE
PNG_FILTER_SUB
PNG_FILTER_UP
PNG_FILTER_AVG
PNG_FILTER_PAETH
PNG_ALL_FILTERS
The documentation simply says, "A special PNG filter, used by the imagepng() function" for each of them.
It seems that using PNG_NO_FILTER will reduce the filesize of the output, but other than that, I am unsure as to how it is affected. Any insight would be really appreciated.
I'm running my own (albeit, basic) benchmarks in a linux-based sandbox. However, I'd love to find a per-function or per-task performance / benchmark reference or utility for comparison.
Does this exist?
Of course I've done my own fair diligence / searching and have so far come up empty handed..
(I'm primarily interested in information relevant to PHP 5.3)
Thanks very much! :)
The standard doesn't specify the order of evaluation of arguments with this line:
The order of evaluation of arguments is unspecified.
What does
Better code can be generated in the absence of restrictions on
expression evaluation order
imply?
What is the drawback in asking all the compilers to evaluate the function arguments Left to Right for example? What kinds of optimizations do compilers perform because of this undefined spec?
Hi,
I have a WPf Toolkit-datagrid..in my application which follows MVVM pattern.
How I can call a function in view-model if user selects a particular row in datagrid ?
Hi, everyone:
As the title described, how to use c library function fgets in assembly language? Indeed, I want to know how to get the file pointer to stdin. Thanks for your reply.
is there a built in function in php that would combine 2 strings into 1?
example: $string1 = abcde, $tring2 = cdefg
combine to get: abcdefg
if the exact overlapping sequence and the position are known, then it is possible to write a code to merge them.
TIA
In statistical language R, mean() and median() are standard functions which do what you'd expect. mode() tells you the internal storage mode of the R object, not the value that occurs the most in its argument. But surely there is a standard library function that implements mode for a vector (or list).
I am attempting to code some plugins to use with MIDI sequencers but have hit a stumbling block. I can't use global-scope variables to store information because multiple instances of the .dll can exist which share memory.
How do I create a class (for re-usability purposes in other plugins) containing 2 dimensional array and other variables the content of which is to be shared between functions? If that is possible, how would I read and write the data from the function in the framework where I do the processing?
I have a function foo(i) that takes an integer and takes a significant amount of time to execute. Will there be a significant performance difference between any of the following ways of initializing 'a':
a = [foo(i) for i in xrange(100)]
,
a = map(foo, range(100))
, and
vfoo = numpy.vectorize(foo)
vfoo(range(100))
? (I don't care whether the output is a list or a numpy array).
Is there some other better way of doing this?
Thanks.
I have two user controls I have some functions written on those two controls. Is it possible to invoke a function written on one user control from another user control. Pls provide the code for this.
Hello All,

I am not creating the child window myself but displaying the contents of some other url.
hi i'am begginer in pYthon and openerp , i want to call a function exists in another class
for example:
i have 2 class :
class a:
def notif_personne_event(self, cr, uid,ids,context=None):
and
import a
class b:
notifier(self, cr, uid,ids,context=None):

but when i do this an error is displayed telling me that class b have not an attribute notifiernotif_personne_event()
someone help me please
I just got this question on a interview and had no idea how to calculate the answer.
How many additional function calls does fib(n) require if "LINE 3" is removed? The answer should be in terms on n.
int fib(int n) {
if(n == 0) return 0;
if(n == 1) return 1;
if(n == 2) return 1; //LINE 3 HERE <---
return fib(n - 1) + fib(n - 2);
}
Find the errors from following C function :
char* f(int i) {
int i;
char buffer[20];
switch ( i ) {
1: strcpy( buffer, "string1");
2: strcpy( buffer, "string2");
3: strcpy( buffer, "string3");
default:
strcpy(buffer, "defaultstring");
}
return buffer;
}
this is c funtion not C++, I think it has to do with type conversion
my compiler give warning that declaration of int i shadows a parameter.
1-which is the parameter that is added to every non-static member function when it is called?
2-what is an adaptor class or wrapper class?
3-what is a non object when can you tell that a memory leak will occur?
4-what is a parameterized type?
I have a char array with data from a text file and I need to convert it to hexadecimal format.
Is there such a function for C language.
Thank you in advance!
I'm trying to setup something like Aspect Oriented Programming in Actionscript 3, basically the only thing I need to be able to do is something like this:
SomeClass.getMethod("methodName").addEventListener(afterMethodExecuted, function() {
//run code
});
This way I can run code after (or before) any method in any class has run, allowing numerous new possibilities.
How should I implement this?
