Let me assume that you know nothing in C
I assume that you know nothing about C programming and also not have any idea of programming. I will begin with the most basic concepts of C and take you up to the high level of C programming including the usually intimidating concepts of pointers, structures, and dynamic allocation.
To fully understand these concepts, it will take a good bit of time and work on your part because they are not particularly easy to grasp, but they are very powerful tools.
Programming in C is a tremendous asset in those areas where you may need to use Assembly Language but would rather keep it a simple to write and easy to maintain program. The time saved in coding of C can be tremendous in such cases.
Even though the C language enjoys a good record when programs are transported from one implementation to another, there are differences in compilers that you will find anytime you try to use another compiler.
Most of the differences become apparent when you use nonstandard extensions such as calls to the DOS BIOS when using MS-DOS, but even these differences can be minimized by careful choice of programming constructs.
When it became evident that the C programming language was becoming a very popular language available on a wide range of computers, a group of concerned individuals met to propose a standard set of rules for the use of the C programming language.
The group represented all sectors of the software industry and after many meetings, and many preliminary drafts, they finally wrote an acceptable standard for the C language. It has been accepted by the American National Standards Institute (ANSI), and by the International Standards Organization (ISO).
It is not forced upon any group or user, but since it is so widely accepted, it would be economic suicide for any compiler writer to refuse to conform to the standard.
The programs written in this book are primarily for use on an IBM-PC or compatible computer but can be used with any ANSI standard compiler since it conforms so closely to the ANSI standard.
