C + + does not allow the return of a complete array as a function parameter. However, you can return a pointer to an array by specifying an array name without an index.If you want to return a one-dimensional array from a function, you must declare a

C + + introduces the three classes of Ostringstream, Istringstream, StringStream, and the sstream.h header file must be included to use them to create an object.The Istringstream class is used for input operations that run C + + style streaming.The

In the previous article we talked about the difference between a value type and a reference type, which we'll look at in depth to see what's different.Let's summarize the difference between the two:Golden rule:1. Reference types are always assigned
