**Steps in Program Development**

*Program development is a multi step process. The steps are*

*1) Understand the problem*

*2) Develop a solution*

*3) Write the program and test it.*

**1. Understand the problem:***When you are assigned to develop a program for solving a problem, you are given the programming requirements. Study these requirements carefully resolve all doubts and ensure that you have understood it fully as per the user requirements.*

**2. Develop a solution:***Once you have understood the problem, you have to develop the solution in terms of some programming language. The tools that help in this are:*

*a) Algorithm / Pseudo code*

*b) Flowchart*

*c) Programming Language, like C etc.,*

*d) Test cases*

*a) Algorithm*

*Definition: A method of representing the step-by-step logical procedure for solving a problem in natural language (like English, etc.) is called as an Algorithm.Algorithm can also be defined as an ordered sequence of well-defined and effective operations that, when executed, will always produce a result and eventually terminate in a finite amount of time. On the whole an algorithm is a recipe for finding a right answer to a problem by breaking it down into simple steps.*

**Properties an Algorithm should possess:***a. Generality: The algorithm must be complete in itself so that it can also be used to solve all problems of a specific type for given input data.*

*b. Input / Output: Each algorithm can take zero, one or more input data and must produce one or more output values.*

*c. Optimization: Unnecessary steps should be eliminated so as to make the algorithm to terminate in finite number of steps.*

*d. Effectiveness: Each step must be effective in the sense that it should be primitive (easily convertible into program statement) and can be performed exactly in a finite amount of time.*

*e. Definiteness: Each step of the algorithm, should be precisely and unambiguously stated.*

*b) Flowchart:*

*Definition: It is a diagrammatic representation of an algorithm. It is constructed using different types of symbols.*

**3. Programming and Testing:***A computer program is the sequence of instructions written in a computer language according to the algorithm and computer follows these in carrying out its computations. The process of writing a program is called programming.*

*Steps involved in Computer Programming:*

*1. Problem Understanding*

*2. Problem Definition*

*3. Program writing*

*4. Error analysis*

*5. Validation & Verification*

*6. Documentation & Maintenance*
