There’s no default parameters in ObjC. You can create 2 methods though: -(void)fooWithA:(int)a b:(int)b c:(int)c { … } -(void)fooWithA:(int)a b:(int)b { [self fooWithA:a b:b c:0]; } For C : there’s nothing special added to the C subset by using ObjC. Anything that cannot be done in pure C can’t be done by compiling in ObjC …
Thanks for the quick and helpful answers guys! I just found another fast way to do this too: SELECT STUFF(( SELECT ‘,’ + X + ‘,’ + Y FROM Points FOR XML PATH(”) ), 1, 1, ”) AS XYList Credit goes to this guy: Link
Well, just do this and your problem is solved : document.getElementById(‘buttonLED’+id).setAttribute(‘onclick’,’writeLED(1,1)’) Have a nice day XD
Is the function defined in the header file? So that the actual code is given directly in the function, like this: static int addTwo(int x) { return x + 2; } Then that’s just a way of providing a useful function to many different C files. Each C file that includes the header will get …
The answer is no, you can’t. You could get the behaviour you want using overloads: void f(int a, int b, int c); inline void f(int a, int b) { f(a,b,b); } inline void f(int a) { f(a,a,a); } As for the last question, C doesn’t allow default parameters at all.
In the first case the global keyword is pointless, so that is not correct. Defining a variable on the module level makes it a global variable, you don’t need the global keyword. The second example is correct usage. However, the most common usage for global variables are without using the global keyword anywhere. The global …
With the params keyword. Here is an example: public int SumThemAll(params int[] numbers) { return numbers.Sum(); } public void SumThemAllAndPrintInString(string s, params int[] numbers) { Console.WriteLine(string.Format(s, SumThemAll(numbers))); } public void MyFunction() { int result = SumThemAll(2, 3, 4, 42); SumThemAllAndPrintInString(“The result is: {0}”, 1, 2, 3); } The code shows various things. First of all …
You can use Get External Data (despite its name), located in the ‘Data’ tab of Excel 2010, to set up a connection in a workbook to query data from itself. Use From Other Sources From Microsoft Query to connect to Excel Once set up you can use VBA to manipulate the connection to, among other …
This is what is actually happening: global_list = [] def defineAList(): local_list = [‘1′,’2′,’3’] print “For checking purposes: in defineAList, list is”, local_list return local_list def useTheList(passed_list): print “For checking purposes: in useTheList, list is”, passed_list def main(): # returned list is ignored returned_list = defineAList() # passed_list inside useTheList is set to global_list useTheList(global_list) …
