　　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.
