14.1 Introduction to programming

1. What is a program?

>>A program is a set of instructions that tell the computer to do various things.

2. What is an interpreter? List all interpreted languages in the passage

>>An interpreter is translates high-level instructions into an intermediate form, which it then executes. (Python, Ruby)

3. What is a compiler? List all compiled languages in the passage.

>>A compiler is a computer program that translates code written in a high-level programming language (such as C++ or Java) into machine code that can be run on a computer (C,C++, C#, Java)

4. Name ten top programming languages mentioned in the passage.

>>Java, c, c++, PHP, Visual Basic, Python, C#, JavaScript, Perl, Ruby

5. What is a multi-paradigm language?

>> C++, Python, Ruby, PHP, Visual Basic, JavaScript, Perl

6. What is an object-oriented language?

>>C#, Java, Python, Ruby

7. What is a procedural language?

>> C

8.What is syntax?

>>Syntax refers to the set of rules that define the structure of the code written in a programming language. Syntax specifies how the code should be written, including the rules for naming variables, the use of punctuation, and the arrangement of code into statements and blocks

9.How many kinds of programming language are there? What are they?

>>There are five programming language: Machine language, Assembly language, Low-level languages, High-level languages, Scripting languages.

10. Put all the programming languages mentioned in the passage into correct categories.

  • Low-level languages: C, C++
  • High-level languages: Java, Visual Basic, Python, C#
  • Scripting languages: PHP, JavaScript, Perl, Ruby

Practice

Fill in the blank with a suitable word

Unfortunately, computers cannot(1)…understand….…. ordinary spoken English or any other natural language. The only (2)…language…… they can understand directly is called machine code. This consists(3)…of……. the 1s and 0s (binary codes) that are processed by the CPU.

However, machine code as (4)…a……. means of communication is very difficult to write. For this reason, we use symbolic languages (5)……that… are easier to understand. Then, by (6)…using…… a special program, these languages can be translated into machine code. For example, the so-called assembly languages use abbreviations such(7)…as… ADD, SUB, MPY to represent instructions. These mnemonic codes (8)…are… like labels easily associated with  the items to which they refer.

Basic languages, where the program is similar to the machine code version, are known as low-level languages. In these languages, each instruction is equivalent(9)……to….. a single machine code instruction, and the program is converted into machine code (10)……by… a special program called an assembler. These languages are still quite complex and restricted to particular machines.
