Gitt en streng som input, skriv et program for å konvertere tegnene i den gitte strengen til den heksadesimale ekvivalenten til ASCII-verdier.

ASCII står for American Standard Code for Information Interchange . ASCII er en standard som tildeler bokstaver, tall og andre tegn innenfor de 256 sporene som er tilgjengelige i 8-biters koden. For eksempel har små bokstaver h (Char) en desimalverdi på 104, som er 01101000 i binær og 68 i heksadesimal.
Det heksadesimale eller ganske enkelt heksadesimale nummereringssystemet bruker Base of 16-systemet. Det heksadesimale tallet bruker 16 symboler {0, 1, 2, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F} for å representere alle tall. Her representerer (A, B, C, D, E, F) (10, 11, 12, 13, 14, 15).
Algoritme:
- Initialiser siste sekskantstreng som tom.
- Vurder hvert tegn fra input, cast det inn i heltall. Denne heltallsverdien er ascii-verdien til det tegnet.
- Endre denne heltallsverdien til heksadesimal verdi og legg til denne heksadesimale verdien til den endelige heksadesimale strengen.
