In C, a data abstraction and the operations that perform on it are declared separately-that is, there is no language-supported relationship between data and functions. We speak of this method of programming as procedural, driven by a set of algorithms divided into task-oriented functions operating on shared, external data.

Data and manipulating data(functions) are seperated in C, which means that the language itself does not support assosications between datas and functions. We call this kind of programming method procedual method which is drived by a group of algorithms distributed in many functions oriented functions which manipulate common extern datas.
