Zufallsfunktion in C

In diesem Thema erfahren wir etwas über die Zufallsfunktion und wie wir die Zufallszahl in der Programmiersprache C generieren können. Wie wir wissen, wird die Zufallsfunktion verwendet, um die Zufallszahl zwischen zwei beliebigen definierten Zahlen zu finden. In der Programmiersprache C verfügt die Zufallsfunktion über zwei integrierte Funktionen: rand() und srand()-Funktion. Lassen Sie uns diese Funktionen in der C-Sprache verstehen.

Zufallsfunktion in C

rand()-Funktion

Im C-Programmiersprache , die Funktion rand() ist eine Bibliotheksfunktion, die die Zufallszahl im Bereich [0, RAND_MAX] generiert. Wenn wir die Funktion rand() in einem Programm verwenden, müssen wir sie implementieren stdlib.h Header-Datei, da die Funktion rand() in der stdlib-Header-Datei definiert ist. Es enthält keine Startnummer. Wenn wir also dasselbe Programm immer wieder ausführen, werden dieselben Werte zurückgegeben.

Escape-Zeichen Java

Hinweis: Wenn die Zufallszahlen mit der Funktion rand() generiert werden, ohne die Funktion srand() aufzurufen, werden bei jeder Programmausführung dieselben Zahlenfolgen zurückgegeben.

Syntax

 int rand (void) 

Die Funktion rand() gibt die zufälligen Ganzzahlen zurück, deren Bereich von 0 bis RAND_MAX reicht. RAND_MAX ist eine symbolische Konstante, die in der Header-Datei stdlib.h definiert wird und deren Wert je nach C-Bibliothek größer, aber kleiner als 32767 ist.

Generieren Sie die Zufallszahlen mit der Funktion rand()

Schreiben wir ein Programm, um die Zufallszahl mithilfe der Funktion rand() zu ermitteln.

ob

 #include #include #include void main() { // use rand() function to generate the number printf (' The random number is: %d', rand()); printf ('
 The random number is: %d', rand()); printf (' 
 The random number is: %d', rand()); printf ('
 The random number is: %d', rand()); getch(); } 

Ausgabe

 The random number is: 41 The random number is: 18467 The random number is: 6334 The random number is: 26500 

Generieren Sie 5 Zufallszahlen mit der Funktion rand()

srand()-Funktion

Die Funktion srand() ist eine C-Bibliotheksfunktion, die den Ausgangspunkt für die Generierung verschiedener Reihen von Pseudozufallszahlen bestimmt. Eine srand()-Funktion kann nicht ohne die Verwendung einer rand()-Funktion verwendet werden. Die Funktion srand() ist erforderlich, um den Wert des Startwerts nur einmal in einem Programm festzulegen, um die verschiedenen Ergebnisse zufälliger Ganzzahlen zu generieren, bevor die Funktion rand() aufgerufen wird.
