The `ifstream` class is used to read input from a file using C++ programming language. It is a part of the C++ standard library, which is included in most C++ compilers.

Here are some examples of using the `ifstream get` function to read input from a file:

Example 1: Reading a single character from a file

#include 
#include 

int main() {
    std::ifstream inputFile("filename.txt");
    char c;

   // Read a single character from the file
    inputFile.get(c);

    std::cout << "Read character: " << c << std::endl;

    return 0;
}

In this example, we open a file named `filename.txt` and read a single character from it using the `get` function. The character is then printed to the console.

Example 2: Reading a string from a file

#include 
#include 

int main() {
    std::ifstream inputFile("filename.txt");
    std::string s;

    // Read a string from the file
    std::getline(inputFile, s);

    std::cout << "Read string: " << s << std::endl;

    return 0;
}

In this example, we open a file named `filename.txt` and read a line of text from it using the `getline` function. The line of text is then printed to the console. The `ifstream` class is part of the standard C++ library, which is included with most C++ compilers. No additional package or library is required.
