 “C Language”Myths: ◦ C Language is difficult.  Typically, C training education includes difficult or unusable contents. Also it uses grimmer-centered way of thinking  Ex. file input/output function and file struct ◦ C Language is not interesting.  Induce making a C programming rely on standard input/output function from beginning to end  All it shows is all numbers or characters on computer screens are boring.  However, C Language is: ◦ An essential yet fun requirement for IT students.

 Students are more motivated from excitement.  To do this: ◦ Something appealing to their eyes ◦ Including Movement, and ◦ Sound  The best toolare “Robots”
