CharMix Function

Return a string whose odd-numbered characters and even-numbered characters are from 2 different strings.

Namespace: XSharp.Core
Assembly: XSharp.Core (in XSharp.Core.dll) Version: 2.19

Syntax

Copy

 FUNCTION CharMix(
	cOdd AS STRING,
	cEven AS STRING
) AS STRING

public static string CharMix(
	string cOdd,
	string cEven
)

Request Example View Source

Parameters

cOdd: Type: String
The string whose characters will constitute the odd-numbered characters in the returned string.
cEven: Type: String
The string whose characters will constitute the even-numbered characters in the returned string.

Return Value

Type: String
A string in which characters from cOdd and cEven appear alternately.
The length of cOdd determines the length of the returned string: the length is twice the length of cOdd, assuming that cEven contains at least one character: A longer cEven string is cut down to the length of cOdd. A shorter cEven is processed from beginning to end, wrapping to the beginning again until there are no more characters in cOdd. If cEven contains less than one character, a NULL_STRING is returned.

Remarks

CharMix() provides a convenient way to recombine strings extracted from CharOdd() and CharEven().

Examples

This example mixes 2 strings:

Copy

1? CharMix("13579", "24680")    // 1234567890

This example shuffles the cards in a game:

Copy

 1Function Start()
 2    LOCAL cPoker AS STRING
 3    cPoker := "AKJQ0123456789"
 4    ? Shuffle(cPoker, 10)    // Q37A048K159J26
 5    RETURN TRUE
 6FUNCTION Shuffle(cDeck AS STRING, ;
 7        siShuffles AS SHORTINT) AS STRING PASCAL
 8    // Assumes even number of cards.
 9    // Length of cDeck is divisible by 2
10    LOCAL siCounter AS SHORTINT
11    LOCAL siCards AS SHORTINT
12    siCards := SLen(cDeck)
13    // First and last cards are not shuffled;
14    // so add/pad blank cards
15    siCards += 2
16    cDeck := PadC(cDeck, siCards)
17    FOR siCounter := 1 UPTO siShuffles
18        // Cut the deck in half and shuffle
19        cDeck := CharMix(Substr3(cDeck, 1,;
20        siCards/2), Substr2(cDeck, (siCards/2)+1))
21    NEXT
22    RETURN Substr3(cDeck, 2, siCards-2)
23    // Exclude added blank cards
