because c is step by step process
C is sequential id est procedural - it has no abstraction layer to facilitate the object oriented programming paradigm... However this can be coded in if required and is - in the case of objective C. Procedural or sequential programming basically means that the program in question is broken down into a sequence of steps or instructions and these are followed in order to make the program function. This is done in a linear fashion.Due to being sequential and procedural C does not have the "Bloat" of the C++ object oriented programming model. Therefore the programs are smaller and generally faster.
I am guessing you typed the question wrong, the way I understand your question is "Why is the programming language named C++ and not C ? " The answer to this is that there is a programming language called C, and in that programming language the ++ means increment by one. So C++ is the language C improved, as such it can read and compile all C programs in addition to having other features that C does not have.
In the early days of computing, the dominant programming languages weresequential(such as basic or assembly language). A program consisted of a sequence of instructions, which were executed one after the other. It ran from start to finish on a single processor.reference: http://code.google.com/edu/parallel/mapreduce-tutorial.html
C derives from a programming language called B, that existed before it. Since C was something of a successor to it, to indicate the advancement from B., the language is called C, the next letter.
Turbo C is a compiler for a general purpose computer programming language called C. It transforms code written in C into the computer language needed for executable programming.
C - programming language - was created in 1972.
Android is programmed in the C and C++ programming language.
Sequential style, or function-oriented. Which is opposed to object-oriented, as in C++.
C++ is the name of a programming language.
C is a programming language.
example of procedural programming are those programming language that have structure e.g basic,fortran,c++,c and pascal e.t.c
