The document outlines the key steps involved in developing a computer program: defining the problem, analyzing requirements, designing an algorithm, coding, debugging, testing and validating, documenting, and maintaining the program. It describes each step, including defining the problem statement and requirements, determining necessary variables and functions, writing step-by-step procedures, implementing the code, checking for errors, validating results, and upgrading the program based on changing needs. Developing a program requires precisely following these steps in order to provide clear instructions that the computer can execute to solve the defined problem.

2.  How program develops
 Various phases to develop a program
 Importance of each phase while developing

3.  You will able to define the various steps
involved in Development of a Program.
 Why these steps are needed.
 What is the importance of each of the step
defined .

4.  Defining the Problem Solving
 Various steps involved in developing a
program.

5.  A computer program is a set of instructions
which a computer can use to solve a problem.
 Programs must be written in a precise way
because computer follows only the
instructions given to it.

6.  Problem Definition
 Problem Analysis
 Designing an algorithm
 Coding
 Debugging
 Testing and Validating
 Documentation and Maintenance.

8.  In this phase, we define the problem
statement and we decide the boundaries of
the problem. In this phase we need to
understand the problem statement, what is
our requirment, what should be the output
of the problem solution. These are defined
in this first phase of the program
development life cycle.


9.  In this phase Analysis takes place and make
sure the new system will meet the
requirements of the end users. In this phase,
we determine the requirements like variables,
functions, etc. to solve the problem. That
means we gather the required resources to
solve the problem defined in the problem
definition phase. We also determine the
bounds of the solution.

10.  We develop a step by step procedure to solve
the problem using the specification given in
the previous phase. This phase is very
important for program development. That
means we write the solution in step by step
statements.
 Flowcharts and Algorithms are used in this
step.

11.  The actual program is written in the required
programming language with the help of
information depicted in flow charts and
algorithms.

12.  There is a possibility of occurrence of errors in programs.
These errors must be removed to ensure proper working
of programs. Hence error check is made. This process is
known as “Debugging”.
 Types of errors that may occur in the program are:
 Syntactic Errors: These errors occur due to the usage of
wrong syntax for the statements.
 Logical Errors: These Errors occur due to incorrect usage
of the instruction in the program. These errors are neither
displayed during compilation or execution nor cause any
obstruction to the program execution. They only cause
incorrect outputs.

13.  Testing and Validation is performed
to check whether the program is producing
correct results or not for different values of
input.

14.  Maintenance is the process of upgrading the
program according to the changing
requirements.
 That means in this phase, the program is
used by the end user. If the user encounters
any problem or wants any enhancement ,
then we need to enhance those things that
are needed by End User or Client so we have
to repeat all the phases from the starting.

15.  We have seen main steps for developing a
program and importance of each step is very
much crucial.
 These are the steps that are used for
developing any kind of a software or website
or anything you want to.
