iikrllx / binout

A simple C program (Bits Manipulation) with debanization.

binout

This simple program works with decimal numbers converting them to binary. The input data are decimal numbers, and the output is binary numbers. This program can help beginners understand binary numbers. However, I would recommend using a gdb shell instead, as gdb has more functions for working with numbers. For example:

$ gdb
$ help x                 # for familarization
$ print /t 3             # 11 (binary)
$ print /x 255           # oxff (hexadecimal)
$ print /o 255           # 0377 (octal)
$ print /d 0Xff          # 255 (decimal)
$ print 0b11111111       # 255 (decimal)

Testing

Let's go back to binout =)

Project cloning, preparation and testing:

$ git clone https://github.com/iikrllx/binout.git
$ cd binout; make; cd src
$ ./binout --help

Check bit:

$ ./binout -c 1234
10011010010(1234)

Find the flag between the two decimal numbers:

$ ./binout -f 1234 14
Flag found:
       1110(14)
10011010010(1234)

Unset the bit in the desired position:

$ ./binout -p 5 -u 32
(0)

Set the bit in the desired position:

$ ./binout -p 18 -s 32
1000000000000100000(262176)

Installing the package in Debian

If necessary, you can build a deb package with this program:

$ fakeroot dpkg-buildpackage -b -uc
$ sudo apt install ../binout_1.0_amd64.deb
