size

When I try to run this, it gives me an error saying that the value in variable a isn't constant. That doesn't make sense to me because I explicitly made the variable a constant. Does the size of an array have to more constant than that? Meaning, only #define a 5 , or initializing it as int arr[5] or using malloc ? What is wrong with what I did? int main{ const int a = 5; int i; int arr [a]; for (i = 0; i < 5; i++) { arr[i] = i * 2; } printf("%d", arr[1]); return 0; } In C, const should be read as read-only . It doesn't define a compile time. const int a = 5; Here a , is not a constant

I am making my app 'universal' (used on iPhone and iPad) and I have found ways of increasing the size of everything except for UISwitches. Is there a way of doing so? Any help is greatly appreciated. kabiroberai According to this answer by the user mxg , just use the following code: mySwitch.transform = CGAffineTransformMakeScale(0.75, 0.75) Of course, you have to change mySwitch to whatever the name of your variable/IBOutlet is. Swift 3 / 4: switch.transform = CGAffineTransform(scaleX: 0.75, y: 0.75) Xcode 9.2 & Swift 4 switch.transform = CGAffineTransform(scaleX: 0.75, y: 0.75) Making a

I came across this question about the underlying types of enums, where an answers quotes Standard C++ 7.2/5 as: The underlying type of an enumeration is an integral type that can represent all the enumerator values defined in the enumeration. It is implementation-defined which integral type is used as the underlying type for an enumeration except that the underlying type shall not be larger than int unless the value of an enu- merator cannot fit in an int or unsigned int. This is pretty clear for all reasonable cases. But what happens if I make an enum so ridiculously large that it can't even

How can I programatically obtain the default height of an UIPickerView instance, in accordance to the resolution and orientation of the device that the app is currently running on? I would like not to use a hardcoded value for this parameter, in the event that new devices will support different screen resolutions and thus will determine this component to have a different default size. The warning that André saw doesn't seem to happen anymore (XCode 4.2; iOS SDK 5.0). If you create it with initWithFrame and give it a height of zero, you can then read back it's height from the frame.height

The Rust documentation is vague on bool 's size. Is it guaranteed to be 1 byte, or is it unspecified like in C++? fn main() { use std::mem; println!("{}",mem::size_of::<bool>()); //always 1? } Rust emits i1 to LLVM for bool and relies on whatever it produces. LLVM uses i8 (one byte) to represent i1 in memory for all the platforms supported by Rust for now. On the other hand, there's no certainty about the future, since the Rust developers have been refusing to commit to the particular bool representation so far. So, it's guaranteed by the current implementation but not guaranteed by any

im working on delphi 7 and i was working on a strings, i came across this For a string of default length, that is, declared simply as string, max size is always 255. A ShortString is never allowed to grow to more than 255 characters. on delphi strings once i had to do something like this in my delphi code (that was for a really big query) var sMyStringOF256characters : string; ilength : integer; begin sMyStringOF256characters:='ThisStringisofLength256,ThisStringisofLength256,.....' //length of sMyStringOF256characters is 256 end; i get this error [Error] u_home.pas(38): String literals may

I am using FOP version 1.0 to create PDFs. In one of the pages I'd like to display an image (2552 x 4200 pixel) and scale it down if it doesn't fully fit on the page. As far as I could see on the mailing list the recommended way of doing this would be following: <fo:external-graphic inline-progression-dimension.maximum="100%" content-height="scale-down-to-fit" content-width="scale-down-to-fit" src="..."/> Unfortunately, that still doesn't display the whole image. The lower part of the image is cut off. Can anyone give me a hint on what I am potentially doing wrong? I found this page here
