Question

how do i convert a decimal (integer) to a hexadecimal? To an octal? to a binary?

Answer 1

unsigned integer

Answer 2

best explains by example 42 decimasl = 42 / 8 = 5 renainder 2 = 52 octal
42 decimal = 42/16 = 2A hexadecimal
the digits i hexadecimal range from 0 -9 then A,B,C,D E F

Answer 3

Answer 4

42 decimal to binary
32 16 8 4 2 1
1 0 1 0 1 0

Answer 5

in binary there is only 2 digits 0 and 1
so
10 = 2^1 + 0 = 2 decimal
11 = 2^1 + 1 = 3 decimal
111 = 2^2 + 2^1 + 2^0 = 4 + 2 +1 = 7 decimal
