The familiar curry :: ((a,b) -> c) -> a -> b -> c curry = \f a b -> f (a,b) function can be generalized to tuples of arbitrary arity, for example: curry3 :: ((a, b, c) -> d) -> a -> b -> c -> d curry4 :: ((a, b, c, d) -> e) -> a -> b -> c -> d -&gt...

First, add Fresco to your build.gradle as shown in the Remarks section: If you need additional features, like animated GIF or WebP support, you have to add the corresponding Fresco artifacts as well. Fresco needs to be initialized. You should only do this 1 time, so placing the initialization in y...

CHAR(n) is a string of a fixed length of n characters. If it is CHARACTER SET utf8mb4, that means it occupies exactly 4*n bytes, regardless of what text is in it. Most use cases for CHAR(n) involve strings that contain English characters, hence should be CHARACTER SET ascii. (latin1 will do just ...

The DATE datatype comprises the date but no time component. Its format is 'YYYY-MM-DD' with a range of '1000-01-01' to '9999-12-31'. The DATETIME type includes the time with a format of 'YYYY-MM-DD HH:MM:SS'. It has a range from '1000-01-01 00:00:00' to '9999-12-31 23:59:59'. The TIMESTAMP type is...

Consider following is our function call. FindArea(120, 56); In this our first argument is length (ie 120) and second argument is width (ie 56). And we are calculating the area by that function. And following is the function definition. private static double FindArea(int length, int width) ...

Consider preceding is our function definition with optional arguments. private static double FindAreaWithOptional(int length, int width=56) { try { return (length * width); } catch (Exception) { thro...

Arrays are zero-based, that is the index always starts at 0 and ends with index array length minus 1. Thus the following code will not output the first element of the array and will output garbage for the final value that it prints. #include <stdio.h> int main(void) { int x = 0; ...

An integer type which is "large enough to store any member of the implementation’s basic character set". It is implementation-defined whether char is signed (and has a range of at least -127 to +127, inclusive) or unsigned (and has a range of at least 0 to 255, inclusive). const char zer...

C11 The function specifier _Noreturn was introduced in C11. The header <stdnoreturn.h> provides a macro noreturn which expands to _Noreturn. So using _Noreturn or noreturn from <stdnoreturn.h> is fine and equivalent. A function that's declared with _Noreturn (or noreturn) is not allowe...

Sometimes a poorly designed 3rd-party library will write unwanted diagnostics to System.out or System.err streams. The recommended solutions to this would be to either find a better library or (in the case of open source) fix the problem and contribute a patch to the developers. If the above solu...

C++11 An unsigned integer type with the same size and alignment as uint_least16_t, which is therefore large enough to hold a UTF-16 code unit. const char16_t message[] = u"你好，世界\n"; // Chinese for "hello, world\n" std::cout << sizeof(message)/sizeof(char16_t) ...

C++11 An unsigned integer type with the same size and alignment as uint_least32_t, which is therefore large enough to hold a UTF-32 code unit. const char32_t full_house[] = U"🂣🂳🂨🂸🃈"; // non-BMP characters std::cout << sizeof(full_house)/sizeof(char32_t) <<...

Some character may be reserved for HTML and cannot be used directly as it may obstruct the actual HTML codes. For example, trying to display the left and right angle brackets (<>) in the source code may cause unexpected results in the output. Similarly, white spaces as written in the source co...

Sometimes you may need to convert a Set to an array, for example to be able to use Array.prototype methods like .filter(). In order to do so, use Array.from() or destructuring-assignment: var mySet = new Set([1, 2, 3, 4]); //use Array.from const myArray = Array.from(mySet); //use destructuring-a...
