Binary conversion-c++

The boring history class has compiled a binary conversion software, the software is relatively single, only decimal to binary, octal, hexadecimal conversion.

With the convenience of C4droid, the APK is generated directly, Andro-all.

Next project, make a Visual basic-based conversion.

Wait for the wind to come.
