Binary to Decimal Conversion
Sometimes in a program, the output is in the form of binary number system. Such output is really comfortable for a computing machine to understand but user can not understand such kind of output form i.e. binary output, hence if our program is generating a binary output a functional logic should be written in order to convert that binary to decimal number system.
