In diesem Thema werden die ASCII-Codes und das Schreiben eines Programms zum Drucken einer ASCII-Tabelle in der Programmiersprache C erläutert. ASCII steht für Amerikanischer Standardcode für den Informationsaustausch . ASCII-Code ist ein Zeichenkodierungsschema, mit dem der Wert grundlegender Zeichenelemente für den Informationsaustausch in Computern und anderen elektronischen Geräten definiert wird.
Darüber hinaus ist der ASCII-Code eine Sammlung von 255 Symbolen im Zeichensatz, unterteilt in zwei Teile, den Standard-ASCII-Code und den erweiterten ASCII-Code. Der Standard-ASCII-Code reicht von 0 bis 127 und ist 7 Bit lang, und der erweiterte ASCII-Code von 128 bis 255 ist 8 Bit lang. Diese Zeichen sind eine Kombination aus Symbolbuchstaben (Groß- und Kleinbuchstaben (a-z, AZ), Ziffern (0-9), Sonderzeichen (!, @, #, $ usw.), Satzzeichen und Steuerzeichen. Daher haben wir Man kann sagen, dass jedes Zeichen seinen eigenen ASCII-Wert hat.
Wenn wir beispielsweise eine Zeichenfolge als „HALLO“ eingeben, speichert der Computer die von uns eingegebene Zeichenfolge nicht direkt. Stattdessen speichert das System die Zeichenfolgen in ihrem entsprechenden ASCII-Wert, beispielsweise „7269767679“. Der ASCII-Wert von H ist 72, E ist 69, L ist 76 und O ist 79.
