Beschreibung

This book equips readers with efficient, well-structured program logics using flowcharts and algorithms. Flowcharting helps create sequences of steps to solve problems through arithmetic and logical manipulations, essential for instructing computers. Applied examples from various subjects encourage readers to grasp the logic leading to solid programming basics.
The course begins with an introduction to programming, moving on to problems involving selection, looping, and arrays. It concludes with the art of file processing. Each chapter builds on the previous one, ensuring a comprehensive understanding of programming logic and flowcharting techniques.
Understanding these concepts is crucial for developing effective computer instructions. This book transitions readers from basic to advanced problem-solving skills, combining theoretical knowledge with practical examples. It is an essential resource for mastering programming logic and flowcharting.

PREFACE

The inspiration for this book came from my students, who asked that I write such a book so that others can grasp the art of programming logic development easily and quickly. This book is aimed at inculcating problem-solving skills in beginners in computing science who might be ill-prepared to handle the problem-solving aspects of the discipline.

Although no book can be claimed to be self-contained, an attempt has been made to equip the readers with all the best, most efficient, and well-structured programming logic in the form of flowcharts and algorithms. The illustrative examples will definitely encourage and enable students to solve the problems in the exercises (and they will enjoy the task). As the task of logic development is an art, the same problem can be solved in a number of ways. Self-starters may try different logical approaches to the solutions or instructors may guide the readers to redevelop the solutions using different approaches.

Suggestions for improvement of this work are greatly appreciated.

CHAPTER 1

INTRODUCTION TO PROGRAMMING

INTRODUCTION

A computer program is a sequential set of instructions written in a computer language that is used to direct the computer to perform a specific task of computation.

Observe that the definition demands that any set of instructions must be such that the tasks will usually be performed sequentially unless directed otherwise. Each instruction in the set will express a unit of work that a computer language can support. In general, high level languages, also known as 3GLs, support one human activity at a time. For example, if a computational task involves the determination of the average of three numbers, then it will require at least three human activities, viz., getting the numbers, obtaining the sum of the numbers, and then obtaining the average. The process will therefore require three instructions in a computer language. However, it can be done using two instructions, also: first by obtaining the numbers and second by obtaining the sum and the average.

The objective of programming is to solve problems using computers quickly and accurately.
