Today I was solving a problem with bitset which needs to find the first set bit (bit with value 1/true). I looked up in C++ Reference but was not able to find a proper function.
Some one else told me that ._Find_first()
works (also mentioned in this blog), which is not documented.
I was curious about if there are more undocumented member functions, so I took a look at the source code and found this:
I think the last question is so funny lol
It is reference to this
I'm a Chinese and I know the Chinese saying "One hand can't make a sound", however, I did't realize it when I was reading the English version of bitset..
One hand can't make a sound
How about using one hand to snap fingers ? (just a harmless idea with no offense in it)
Sorry, the translation should be "A hand can't make sound by clapping" or "A slap won't clap"..
I didn't hear anything :(
