I didn't know what it is. Just learnt it. It shifts the bits. For
example (in python shell):
3 >> 1 # 00 00 00 11 moves 1 bit right 00 00 00 00 01
#Output: 1
3 << 1 # 00 00 00 11 moves 1 bit left 00 00 00 01 10
#Output: 6
# you can experiment with numbers:
1 << 1
#Output: 2
1 << 2
#Output: 4
Aren't you guys talking about the shell. I guess he is asking about C.
(I don't know if it is same for C and shell)

It is a standard I/O redirector. It means "append this output to the end of
that file".
Suppose, someone has a file named a.txt and a.txt has a value X in it. Now,
if we run
echo 'Y' > a.txt
it will replace the file a.txt and will have value Y. And if we run
echo 'Y' >> a.txt
it will append '2
You should specify where, in C++ right? Or in linux shell?
