 Let's have a look at the following sample program. All you have to do is to add a function pointer such as "calculate" to the definition of struct "something_s". Later, during the struct initialization, assign a function address to that function pointer:
 
-```

 #include <stdio.h>

 As you can see, you can call the function (pointed by the function pointer) with the same syntax as in C++ or Java:
 
-```
+```c
 printf("%s(%f, %f) => %f\n", mult.name, a, b, mult.calculate(a,b));
 printf("%s(%f, %f) => %f\n", div.name, a, b, div.calculate(a,b));
 ```
 
 However, that's just syntactic sugar for:

 printf("%s(%f, %f) => %f\n", mult.name, a, b, (*mult.calculate)(a,b));
 printf("%s(%f, %f) => %f\n", div.name, a, b, (*div.calculate)(a,b));

 However, that's not really how it works in object-oriented languages such as Java and C++. The method call in this example is not a method call as "mult" and "div" in this example are not "message receivers". I mean that the functions can not access the state of the "mult" and "div" struct objects. In C, you would need to do something like this instead if you wanted to access the state of "mult" from within the calculate function, you would have to pass it as an argument:
 
-```
+```c
 mult.calculate(mult,a,b));
