1. INTRODUCTION

   • To solve a problem, a sequence of instructions is communicated to the computer. To communicate these instructions, programming languages are developed. The instructions written in a programming language comprise a program.

2. PROBLEM DOMAIN AND SOLUTION DOMAIN

   • A problem is a functional specifi cation of desired activities to generate the intended output

3. Problem States

   • The problem has a start state and an end state or goal state. The solution helps the transition from the start state to the end

4. TYPES OF PERSONS ASSOCIATED TO A SOLUTION

   • The people developing solution are called developers and the people using the solution are called users. The developer is also known as supplier, or programmer, or implementer. The user is also called client, or customer, or end-user. The solution represents the instructions to be followed to generate the output. The solution of a problem should be carefully planned to enable the user to gain confi dence in the solution. Fig
