Good night:
I'm trying to make a homework but I couldn't create the algoritm.

Wanted is this: Entered as an input Binary(2), Octal(8), Hexadecimal(16) or Decimal(10), knowing which format is and converting to other formats...

For example; user enters 0100010.
program must give an output that says "this is a binary number".
and the equals in decimal, hexadecimal and octal.

EXAMPLE RUN:
Enter a number: 0100010
It is a binary number.
Octal of 0100010 is: XXXXXX.
Hexadecimal of 0100010 is YYYYYY.
Decimal of 0100010 ZZZZZ.

thank you..
