Question

Write a program which first converts Binary number to Hexadecimal number then convert that Hexadecimal number into Octal number and Decimal number (In Python and c++)​

Answer 1

Answer:

It's fairly straightforward to do the conversion from binary in pure bash (echo and printf are builtins):

Binary to decimal

$ echo "$((2#101010101))"

341

Binary to hexadecimal

$ printf '%x\n' "$((2#101010101))"

155

Going back to binary using bash alone is somewhat more complex, so I suggest you see the other answers for solutions to that.
