How to make char into integer and then define what kind of number is it(decimal, binary, hexadecimal). Then translate them into other two(i.e. i have decimal and i must translate it in binary and hexadecimal) and only by shifting. I cannt get this theme. Help

Answer 1

char to String and then to Int
you have to make two functions
if you want to convert to binary and hexadecimal
hexadecimal is easy
use a switch
with the 15 elements in hexadecimal!
