reentrant functionsIn the design of real-time systems, multiple tasks often call the same function. If this function is unfortunately designed to be a non-reentrant function, then different tasks calling this function may modify the data of other
For: Ostream & operator Description: 1. The first parameter is a reference to the Ostream object, and the output is generated on that object, Ostream is non-const, because writing to the stream alters the state of the stream; The parameter is a
