  • FORTRAN (VCSU-MEP)
    an assignment statement resembles an equation This made it much easier for many programmers to become familiar with the language It also influenced most of the programming languages that followed it FORTRAN was and is widely used for numerical processing which was the main task of computers in the 1950s During the 1960s most of the development of programming languages was in correcting the perceived flaws of FORTRAN This should

  • An alternative: LISP (VCSU-MEP)
    small enough to fit on a single sheet of paper Although LISP came slightly after FORTRAN it owes nothing to the FORTRAN effort in either implementation or inspiration LISP has historically been implemented as an interpreter although compilers do exist It is the dominant Artificial Intelligence language It is also the first example of the Functional paradigm of programming languages Most programming languages never have substantial popularity Only a few

  • Why is any translation needed? (VCSU-MEP)
    its own machine language A machine language instruction may cause two numbers to be added or a value to be copied to an output device or many other very simple operations However writing programs in machine language is extremely tedious and time consuming In the 1950s assembly language was invented Assembly language is just machine language made easier to write Instead of a number such as 47 you use a

  • The Compilation Process (VCSU-MEP)
    are specific to one particular language such as the FORTRAN compiler or C compiler There are usually about four steps running a program editing compiling linking and running Each has an exhibit a Creating or editing the source program b Compiling the source program into object c Linking the objects d Running the program or n Interpretation r Why is compilation or interpretation needed x Exit to introduction exhibit Links

  • Interpretation (VCSU-MEP)
    in one Interpreters are often easier to write than compilers They usually have excellent run time debugging features and they usually interpret the code faster than a compiler can compile link and execute Their largest disadvantage is that the program usually runs slower during interpretation than an equivalent compiled version Hence if you have a choice between a compiler and interpreter for a particular language then use the interpreter during

  • Hybrids of compilation and interpretation (VCSU-MEP)
    for a mythical computer In order to run the program you must run an interpreter for this mythical computer There are several advantages to this approach mostly in the area of machine independence There is only one Java compiler which is itself a Java program that has to be run with the interpreter In order to get Java to run on a new machine all that is needed is to

  • Problem Domain Types (VCSU-MEP)
    may be better suited to be written in one language A rather than language B Another choice of program will reverse the preference What follows is a brief list of such domains and some of their representative languages General purpose

  • Types of Languages (VCSU-MEP)
    C COBOL FORTRAN Pascal etc Functional languages on the other hand use function calls as the basic unit Typically they use very few variables Instead they use function results and almost no assignment statements LISP and Scheme are two prominent
