If you want to solve the computational problem with a computer, you should learn how to program. The task of developing programs for the solution of computational problems is referred to as programming. Computer programming is the process of planning and creating a sequence of steps for a computer to follow.

So programming is breaking a task down into small steps.Programming is sometimes contrasted with (与相比)coding. Coding generally refers to the writing of programs for given program specification, while programming includes the task of preparing the program specification as well as that of writing the program. The text of a program is sometimes referred to as code, and lines of program text are referred to as lines of code, especially in the case of machine-language programs. The term coder is used to describe a person engaged exclusively in implementing program specifications prepared by others. Whats actually involved in programming - the actual process of writing programs? Heres a quick overview of the process: Write a program. Compile the program. Run the program. Debug the program. Repeat the whole process until the program is finished. Choose the best answer according to the passage E.
