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
Say I have a simple object such as
class Something
{
public int SomeInt { get; set; }
}
I have read that using immutable objects are faster and a better means of using business objects? If this is so, should i strive to make all my objects as such:
class ImmutableSomething
{
public int SomeInt { get { return m_someInt; } }
private int m_someInt = 0;
public void ChangeSomeInt(int newValue)
{
m_someInt = newvalue;
}
}
What do you reckon?
Using simple type like
class A {
public int X, Y;
}
with object intializers, one can write
var a = new A { X=0, Y=0 };
But the following is also accepted by the compiler:
var a = new A { X=0, Y=0, }; // notice the additional ','
Same for int[] v = new int[] { 1, 2, };
This looks a bit strange ... Did they forgot to reject the additional ',' in the compiler or is there a deeper meaning behind this?
I am using hibernate annotations. How to add methods to POJO object? For example i have "getChildNodes" method, associated with database, but i want also add recursive method "getAllChildNodes". I get "org.hibernate.PropertyNotFoundException: Could not find a setter for property progress in class" exception when i do it.
I am new to mac, my question is what else text editors can be used to edit object c code except xcode. And which one is the best for productively editing source code?
I understand the purpose of the NULL constant in C/C++, and I understand that it needs to be represented some way internally.
My question is: Is there some fundamental reason why the 0-address would be an invalid memory-location for an object in C/C++? Or are we in theory "wasting" one byte of memory due to this reservation?
In interview someone ask me @ Abstract class. I told him @ abstract class and i also told that we can not create object of this class. his next question is why? because it may or may not include abstract methods.
Say I have:
@property (nonatomic,retain) NSString *foo;
in some class.
And I call:
myclass.foo = [NSString stringWithString:@"string1"];
myclass.foo = [NSString stringWithString:@"string2"];
Should I have called [myclass.foo release] before setting it to "string2" to avoid a memory leak?
Or the fact that nothing is pointing to the first "string1" object anymore is good enough?
And in the dealloc method [foo release] will be called.
Hey,
I am hiding a TextBoxin my aspx page like this:
myField.visible=false;
Now I have a DropDown as well which tries to access the TextBox on IndexChange. The problem is, it cant access the hiffen TextBox and I am getting document.form[0] is Null or Not an Object. How can I solve that? Is the some check for that in JavaScript?
Thanks :-)
I have a dict object. I dumped the data using this:
for alldata in data: # print all data to screen
print data[alldata]
Each field had brackets [] and 'None' values for NULLS and date.datetime for date values.
How do I dump this dict to MySQL table? Thank you!
I would like to use a component that exposes the datasource property, but instead of supplying the datasource with whole list of objects, I would like to use only simple object. Is there any way to do this ?
The mentioned component is DevExpress.XtraDataLayout.DataLayoutControl - this is fairly irrelevant to the question though.
Trying to optimize my MUI 2 NSIS setup in which I do some ExecWait calls in the .onInstSuccess callback function, I was searching through the documentation to find a callback that is called:
after the files are all copied -and-
before the wizard page is being switched from the file copy page to the finish page.
Unfortunately, I found no such callback.
Therefore my question is:
Is it possible to do some custom processing after the files are copied and before the wizard page is being switched away from the file copy page?
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.
<?php
function register_template(){
print_r(func_get_args());
# the result was an array ( [0] => my template [1] => screenshot.png [2] => nice template .. )
}
register_template( # unkown number of arguments
$name = "my template",
$screenshot = "screenshot.png",
$description = "nice template .. "
)
?>
BUT , I want the result array as $key = $value form , $key represents the parameter name.
Example: I have one persistent store coordinator which uses one single persistent store.
Now there are two managed object contexts, and both want to use the same persistent store. Could both simply use the same persistent store coordinator, or would I have to create two instances of NSPersistentStoreCoordinator? And if I had to, then: Would I also have to create two NSPersistentStore instances?
Can I do the following?
public Manager(String userName) {
game = new Game(userName);
game.addManager(this);
}
The problem is that I refer to an object (this) in its constructor (before it was actually created).
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.
I want to detect one kind of object such as person in the picture,
who can tell me how to training a kind of people classifier for use,so we can use the classifier to detect people in any picture.
I have written an application that basically gathers up a bunch of text and numerical data from the client PC and stores it as an object. Right now I'm implementing XML serialization so that the file can be saved.
The issue is now, how do I get this data to the server? I have a server running IIS 7 setup but I don't quite understand the ASP.net life cycle, so I'm not sure how to implement the receiving app.
What should I do?
Thanks
Since there is no way that you can make the flash object transparent, there needs to be some other means by which you can match the background. I thought of maybe creating a ActionScript/Javascript bridge, but I wonder if this is the route to take.
Do I have a better option?
