In a saved search formula, the possible values of mainline are designed to be useful in an HTML context. When mainline is true, the value of {mainline} is the 1-character string * (asterisk). When mainline is false, the value of {mainline} is the 6-character string   (non-breaking space, HT...
We can have three cases to analyze an algorithm:
Worst Case
Average Case
Best Case
#include <stdio.h>
// Linearly search x in arr[]. If x is present then return the index,
// otherwise return -1
int search(int arr[], int n, int x)
{
int i;
for (i=0; i<n; i...
CSS variables cascade in much the same way as other properties, and can be restated safely.
You can define variables multiple times and only the definition with the highest specificity will apply to the element selected.
Assuming this HTML:
<a class="button">Button Green</a>...
In Coq, destruct more or less corresponds to a case analysis. It is similar to induction except that there's no induction hypothesis. Here is a (admittedly rather trivial) example of this tactic:
Require Import Coq.Arith.Lt.
Theorem atLeastZero : forall a,
0 <= a.
Proof.

Go to the test method you want to ignore
Before the @Test annotation, enter @Ignore
optional: You can add description why are you ignoring this test method, something like: @Ignore ("ignoring this test case for now")
a sample method would be:
@Ignore ("not going to test this m...
Here are the steps to generate test skeleton for existing code:
Open Eclipse, and choose the project you want to create test cases for
In the Package Explorer, select the java class you want to generate the Junit test for
Go to File -> New -> Junit Test Cases
Change the Source folder to ...
All strings in Progress ABL are case sensitive unless specified otherwise.
This example will display a message box saying that the strings are identical.
DEFINE VARIABLE str1 AS CHARACTER NO-UNDO.
DEFINE VARIABLE str2 AS CHARACTER NO-UNDO.
str1 = "abc".
str2 = "ABC".

Combining change of character case with Enumeration_IO and using a text buffer for the image. The first character is manipulated in place.

with Ada.Characters.Handling; use Ada.Characters.Handling;

As mentioned before strings are normally case insensitive but that only regards comparison of strings. There's built in functions for changing case.
CAPS (string)
Makes string upper case
LC(string)
Makes string lower case
DEFINE VARIABLE c AS CHARACTER NO-UNDO.
DEFINE VARIABLE d AS C...
The CASE-statement is a lot more strict than the IF/ELSE-conditional. It can only compare a single variable and only equality, not larget/smaller than etc.
DEFINE VARIABLE c AS CHARACTER NO-UNDO.
CASE c:
WHEN "A" THEN DO:
RUN procedureA.
END.
WHEN "B" ...
Type Casting
Type casting is a way to check the type of an instance, or to treat that instance as a different superclass or subclass from somewhere else in its own class hierarchy.
Type casting in Swift is implemented with the is and as operators. These two operators provide a simple and express...
The traditional technique to make sort ignore case is to pass strings to lc or uc for comparison:
@sorted = sort { lc($a) cmp lc($b) } @list;
This works on all versions of Perl 5 and is completely sufficient for English; it doesn't matter whether you use uc or lc. However, it presents a problem ...
This converts valid json strings to MySQL JSON type:
SELECT CAST('[1,2,3]' as JSON) ;
SELECT CAST('{"opening":"Sicilian","variations":["pelikan","dragon","najdorf"]}' as JSON);
Assume we need to add an NSString object to SomeClass (we cant subclass).
In this example we not only create an associated object but also wrap it in a computed property in a category for extra neatness
#import <objc/runtime.h>
@interface SomeClass (MyCategory)
// This is the property wr...
Deconstructing the use of an unsafe pointer in the Swift library method;
public init?(validatingUTF8 cString: UnsafePointer<CChar>)
Purpose:
Creates a new string by copying and validating the null-terminated UTF-8 data referenced by the given pointer.
This initializer does not try to rep...
Use dynamic_cast for converting pointers/references within an inheritance hierarchy.
Use static_cast for ordinary type conversions.
Use reinterpret_cast for low-level reinterpreting of bit patterns. Use with extreme caution.
Use const_cast for casting away const/volatile. Avoid this unless you ar...
