ASCII-tabel in C

In dit onderwerp worden de ASCII-codes besproken en hoe u een programma schrijft om een ​​ASCII-tabel af te drukken in de programmeertaal C. ASCII staat voor Amerikaanse standaardcode voor informatie-uitwisseling . ASCII-code is een tekencoderingsschema dat wordt gebruikt om de waarde van basistekenelementen te definiëren voor het uitwisselen van informatie in computers en andere elektronische apparaten.

Bovendien is de ASCII-code een verzameling van 255 symbolen in de tekenset, verdeeld in twee delen: de standaard ASCII-code en de uitgebreide ASCII-code. De standaard ASCII-code varieert van 0 tot 127, 7 bits lang, en de uitgebreide ASCII-code van 128 tot 255 is 8 bits lang. Deze tekens zijn een combinatie van symboolletters (hoofdletters en kleine letters (a-z, AZ), cijfers (0-9), speciale tekens (!, @, #, $, enz.), leestekens en controletekens. Daarom kan zeggen dat elk teken zijn eigen ASCII-waarde heeft.

Wanneer we bijvoorbeeld een string invoeren als 'HELLO', slaat de computermachine de string die we hebben ingevoerd niet direct op. In plaats daarvan slaat het systeem de tekenreeksen op in hun equivalente ASCII-waarde, zoals '7269767679'. De ASCII-waarde van H is 72, E is 69, L is 76 en O is 79.
