  • Thank you for this tutorial. I was wondering maybe you could help solve task i received at university:

    Write a program that reads in an integer and prints out the given integer in binary, octal and hexadecimal formats.

    your program should do the following tasks:

    * it should accept an integer number from the keyboard
    * change this number to binary, octal and hexadecimal formats
    * it should finally print these three formats to the screen
