+## IF.03.22 Procedural Programming
+# Assignment Pointer Fun
+
+## Objective
+This assignment lets you practise a bit more with the difference between references and values.
+
+## Materials
+- Atom or any other editor
+- gcc
+- terminal.
+
+## Required Tasks
+1. Create a file called `pointer_func.c` and write a `main` function which declares
+   - an integer variable `int_value`
+   - a pointer to an integer `int_pointer`
+
+3. Assign some values to the variables. Take care how to assign a value to the pointer. What is possible there? Describe this briefly in a comment right after this line of code.
+
+2. Define a function `print_integers` which accepts the following paramters
+   - an integer variable `int_value`
+   - a pointer to an integer `int_pointer`
+   
+   The function shall print *the values* (note, also the *value* at the address which is stored in `int_pointer`) of both parameters in the following form
+   `Got an integer value <x> and an address to an integer with value <y>` where `<x>` and `<y>` shall be replaced by the actual values of the parameters passed.
+   
+4. Call the function `print_integers` in the `main` function and test your implementation.
+
+5. Define a function `change_integers` which accepts the same parameters as `print_integers`. In the function body the values of the two parameters shall be changed to some different values.
+
+6. Call the function `change_integers` and then again call `print_integers` at the end of the `main` function. Which values are changed, which are not? Why? Describe this briefly in a comment right after the call of the functions.
+
+7. Describe the five scenarios which can occur when declaring and using variables (declare a value, declare a pointer, get the value, get the value of a pointer, get the pointer of a value). Make a table as follows (two scenarios are already filled out for you to give you a more precise picture what to be done here). Write this table by hand, scan it (or take a photo) and add it to your repository. The name of the file shall be `scenarios.jpg` or `scenarios.png`.
+
+| Declaration/Usage | Scenario | Syntax Example | Description of the Example
+| --- | --- |--- | --- |
+| Declaration | Declaration of a value | `int x` | A variable of type `int` is declared. This variable can hold an integer value |
+| Declaration | | | |
+| Usage | Using a value | `foo(x)` | The function `foo()` is called and the value of a variable `x` is passed to it |
+| Usage | | | |
+| Usage | | | |
+
+## Hints
+- Take care to keep the work loop "Implement a little", "Test a little" to avoid the 100 lines of error mess.
+
+## Extra Credit
+Document your implementation in an extra text file or in an inline comment. In particular:
+- Write down the reasons, how you assigned values to the variables in the main function.
+- Give alternatives how to pass parameters when calling the different functions.
+- Write down the reasons, why some variables are not changed by `change_integers`.
+
+## Evaluation
+All coding assignments will get checked. Most common reasons that your assignment is marked down are:
+
+- Program does not build or builds with warnings
+- One or more items in the *Required Tasks* section are not satisfied
+- Submitted code is visually sloppy and hard to read
+
+## Things to Learn
+- Repeat using primitive data types, like integer, float/doubles
+- Repeat implementing functions
+- Repeat pointer handling on primitive data types
