    System programs are intended to support the operation and use of the computer itself, rather than any particular application. For this reason, they are usually related to the architecture of the machine on which they are to run. Because most system software is machine-dependent, we must include real machines and real piece of software in our study. We will present the fundamental functions of each piece of software based on a Simplified Instructional Computer (SIC) – a hypothetical computer. 1.3…

    The C++ programming language was introduced by Bjarne Stroustrup of the AT&T laboratories in 1985 as an extension of C, with additional features borrowed from the esoteric language Simula. Since then, C++ has grown rapidly in response to the practical need for a programming language that is able to efficiently handle composite and diverse data types. The language implementation is pivoted on the ingenious concept of object oriented programming (OOP). Today, C++ dominates the commercial market and is favored among system programmers and…

    Today's lecture will be a quick history of programming languages. Since 1957 when the first Fortran was introduced for the IBM 704, literaly hundreds of new programming languages have come and gone--well, some of them have gone, and others--like Fortran, have managed to stay around. The sheer number of languages makes it impossible to cover them all in any depth--indeed, even the most important languages we will only have time to discuss in shallow detail today. As a result, we talk about only the most important languages--those that had historical significance either for their new ideas or their influences on the languages that followed them.…
