In order to solve a computational problem, its solution must be specified in terms of asequence of computational steps, each of which may be performed by a human or a digital computer. If you want to solve the computational problem with a computer, you shouldlearn how to program. The task of developing programs for the solution of computationalproblems is referred to as programming. Computer programming is the process of planningand creating a sequence of steps for a computer to follow. In general, this process will helpus resolve a problem, which is either too tedious or difficult to work out otherwise. Soprogramming is breaking a task down into small steps.

Programming is sometimes contrasted with coding. Coding generally refers to thewriting 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 aprogram is sometimes referred to as code, and lines of program text are referred to as lines ofcode, especially in the case of machine-language programs. The term coder is used todescribe a person engaged exclusively in implementing program specifications prepared byothers. What ' s actually involved in programming - the actual process of writing programs？ Here' s 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.
