"Garbage in means garbage out"
                                                    Programmer's  Saying                                                                   
 
       There are several different ways that a  DEV C++ Programming can perform input and output.
     
       Let's describe first what are called"streams". An Input stream is simply the stream of the input that is being fed into the computer for the program to use. The word "stream" suggests that the program processes the input in the same way no matter where the input comes from.

       The intuition for the word "stream" is that the program sees only the stream of input and not the source of the stream, like mountain stream whose water flows past you but whose source  is unknown to you. Similarly, an Output stream is the stream of output generated by the program where in the output is going to a terminal screen.

                
                            SPECIAL CHARACTERS AND SYMBOLS IN DEV C++

                    In Dev C++ programming, it is important to understand also the functions and usage of  "special characters and symbols" that will be useful in doing your program, thus to be able to come up with a good and running program.   Above is the chart showing the special characters ,symbols and its functions.
