Also, a setup file for a "Not-Full"-Version of Visual Basic is contained in the disk. Contained in the disk is the source code for all the examples in the text (so you don't have to type them). The final chapter introduces Visual Basic. The constructions of line charts, bar charts and pie charts are also discussed. Commands such as SCREEN, LINE, and WINDOW are presented. Chapter 9 deals with Random Access Files Chapter 10 deals with graphical display of data. Sorting and merging of sequential files are also presented. Two-Dimensional Arrays are also presented. Sequential search and Binary search are also discussed. Some applications of arrays such as the Bubble sort and the Shell Sort are discussed in this chapter. Arrays are then discussed in the next chapter. a variable to keep track of whether certain event has occurred, FOR.Next Loops and finally a case study on developing a menu-driven program to analyse loan is presented. Variables -Print and LPrint -Strings - Concatenation of strings, ASCII Tables, LEFT$, RIGHT$, MID$, UCASE$, LEN, INSTR, -Data Input - READ and DATA Statements together with RESTORE, INPUT -REM - The use of the REMark Statement -PRINT Statement - Screen Placement and Formatting, PRINT USING, Output to the Printer, -Subprograms - How variables and expressions are passed, passing values from subprograms to the main body, -Functions - INT, CHR$, LEN, MID$, INSTR -Decisions -=,, >, =, IF-THEN-ELSE, ELSE IF, SELECT CASE, Repetition - This chapter discusses Do Loops, how one can process data in a list format with Do Loops, Nested Loops, Flags i.e. Scientific notation - how some large and very small numbers are presented. The rest of the chapters discuss topics like -Numbers - addition, subtraction, division, etc. In this chapter, the use of flowcharts (a very useful programming tool) is introduced. A chapter is then devoted to Problem Solving. Some basic DOS commands are also presented and the biographical history of computing is also discussed. Then the user interface of QBASIC is shown, explaining the use of the Menu Bar, Title Bar, View Window, etc. This book starts off with the introduction to computers such as the definition of personal computer, how one communicates with the computer, how computers perform complicated tasks, etc. If you are new to programming, then this is a good book for you. I have read the third edition of this book.
