Quick printf binary number question

[Jack]

Hello,
I am wondering how to display a binary number with printf. (00000001b)

The specifier should look something like this
printf ("%b\n", a);

Have taken a look at my reference but did not find it
Thanks in advance
Jack

printf won't help you with that. In fact, to the best of my knowledge, there is nothing in C or C++ standard library that could produce a binary representation of an integer. You'll have to roll your own.

Actually the std::bitset has the to_string function. It can help.

Also, the _itoa and _itow family of functions will produce a binary string
when 2 is used as the radix.
