Avand ca data de intrare un sir de caractere , de exemplu ASCII, adica pe 2 octeti, se vrea conversia acestui sir de caractere ASCII la echivalentul lor ca valoare intreaga, pe 4 bytes sau pe 8 bytes.

Se presupune ca sirul de caractere care se vrea trasnformat contine doar caracterele ASCII corespunzatoare cifrelor zecimale adica de la '0' la '9'. Eventual semnul '-' , pentru valori negative.

De exemplu daca avem string-ul "123" acesta se vrea convertit la 123.


Dar pentru un string precum "abc34de" se va lansa o exceptie / returna o eroare.

Functia de conversie va trebui de asemenea sa faca o verificare a domeniului de valori. De exmeplu pentru un string precum : "89564342342341231231322127777"
va da o exceptie, valoarea numerica neputand fi reprezentata pe 4 sau pe 8 octeti (bytes).
