Stringstream is stream class present in C++ which is used for doing operations on a string. It can be used for formatting/parsing/converting a string to number/char etc. Hex is an I/O manipulator that takes reference to an I/O stream as parameter and returns reference to the stream after manipulation. Here is a quick way to convert any decimal to hexadecimal using stringstream:...
