#includeIn this example, we open a file `example.txt` and read the first character from it using the `get()` function. We then use `putback()` to put that character back into the filestream, and read it again using `get()`. The output will be the first character in the file. The `putback()` function is part of the C++ standard library, which is included in the `#include using namespace std; int main() { ifstream myfile("example.txt"); char c; // read a character from the file myfile.get(c); // put it back myfile.putback(c); // read it again myfile.get(c); cout << "The first character in the file is: " << c << endl; myfile.close(); }
