[Solved] What is the use of >>= or

Question

those are called compound assignment operators. There are almost 10 of them in C/C++ language. ex += -= *= <<= >>=. When one of the operand is same as the variable to which final result to be assigned is same, in a binary operation this can be used as a short hand syntax. Ex a=a+b can be written as a+=b. in the same a=a<<2 can be written as a<<=2. This type of syntactic sugar is also supported by other languages too.
