Explain C++ streams and stream classes with an example.
C++ streams and stream classes are essential components for handling input and output operations in C++. They provide a convenient and flexible way to perform input and output operations on various devices, such as the console, files, and other I/O devices. The standard C++ library includes several predefined stream classes that facilitate these operations.
The fundamental stream classes in C++ are `istream` (input stream) and `ostream` (output stream), which are the base classes for more specialized stream classes like `ifstream` (input file stream), `ofstream` (output file stream), and `stringstream` (string stream).
Here's a brief explanation of C++ streams and stream classes with an example:
```cpp
#include <iostream>
#include <fstream>
int main() {
// Output stream example
std::cout
