Thread: Instead of using the high-level languages, programmers will start using the more higher-level programming languages and human language level programming languages?

    Default Instead of using the high-level languages, programmers will start using the more higher-level programming languages and human language level programming languages?

    Hi,

    It is written in book Java How to Program ninth edition that instead of using the strings of numbers that computers could directly understand, programmers began using English-like abbreviations to represent elementary
    operations:

    1.5 Machine Languages, Assembly Languages and High-Level Languages

    Programmers write instructions in various programming languages, some directly understandable by computers and others requiring intermediate translation steps. Hundreds of such languages are in use today. These may be divided into three general types:

    Machine languages
    Assembly languages
    High-level languages
    Any computer can directly understand only its own machine language, defined by its hardware design. Machine languages generally consist of strings of numbers (ultimately reduced to 1s and 0s) that instruct computers to perform their most elementary operations one at a time. Machine languages are machine dependent (a particular machine language can be used on only one type of computer). Such languages are cumbersome for humans. For example, here’s a section of an early machine-language program that adds overtime pay to base pay and stores the result in gross pay:

    +1300042774
    +1400593419
    +1200274027

    Programming in machine language was simply too slow and tedious for most programmers. Instead of using the strings of numbers that computers could directly understand, programmers began using English-like abbreviations to represent elementary
    operations. These abbreviations formed the basis of assembly languages. Translator programs called assemblers were developed to convert early assembly-language programs to machine language at computer speeds. The following section of an assembly-language program also adds overtime pay to base pay and stores the result in gross pay:

    load basepay
    add overpay
    store grosspay

    Although such code is clearer to humans, it’s incomprehensible to computers until translated to machine language. Computer usage increased rapidly with the advent of assembly languages, but programmers still had to use many instructions to accomplish even the simplest tasks. To speed the programming process, high-level languages were developed in which single statements could be written to accomplish substantial tasks. Translator programs called compilers convert high-level language programs into machine language. High-level languages allow you to write instructions that look almost like everyday English and contain commonly used mathematical notations. A payroll program written in a high-level language might contain a single statement such as

    grossPay = basePay + overTimePay

    Instead of using the high-level languages, programmers will start using the more higher-level programming languages and human language level programming languages?

    I probably will create the more higher-level programming and the human language level programming.

    What do you want? I have no comments on your essay.
