Semantics In Programming Language

938 Words4 Pages

The success of the programming language is related with the ease of providing a compact plus simple description of programming language. ALGOL 60 along with ALGOL 68 was initially represented using compact formal descriptions; in both scenarios, however, the representation was not clear since they utilized a completely new notation. Hence both these languages were not accepted well by the developer community. Similarly, few languages have faced issues due to many varying dialects, due to simple yet informal and imprecise representation.
The study of programming languages, similar to natural languages, can be classified into understanding of syntax and semantics. The syntax of a programming language is the combination of expressions, statements, and program units. The semantics provides meaning to the expressions, statements, and program units.
For example, the syntax of a Java in while statement is the semantics of …show more content…

Example of Semantics
• Interpreter
• Compiler
Let us see the difference between syntax and semantics

Syntax Semantics
Syntax is referred to the formal rules for governing the construction in valid statements of language. Semantics is referred to a set of rules which gives the exact meaning of the statement.
It is difficult to learn and understand. It is easy to learn and understand.
Errors are occurred in the program, when the rules are violated. Errors are occurred in the program, when the sentences and statements does not match the form properly.
It has only one approach for performing a job. It has different ways for completing the syntax.
Importance of syntax and semantics in programming languages
A syntax should recognize the program syntax and next it performs semantic analysis. A good programming language syntax includes:
• Avoids Ambiguity
• Recognizes easily
• Easy to scan and

    The hashtag exempts the line from actually running in the program allowing you to make remarks on what’s happening and possibly explain how it works. While talking about code comments one can safely assume that the program itself is a form of writing also. It has its own grammar, or syntax, and lexis about it. The coding community has developed its own style of writing and talking to make writing programs as simple as possible while still being able to carry out complex tasks. The second style of writing in a computer science major would be project proposals.

  • John R. Searle's Minds, Brains And Programs

    1686 Words  | 7 Pages

    He, who cannot read or understand Chinese, is then given a second set of sheets written in Chinese, called a “story”, and a set of rules written in English (the “program”). The rules explain how he can compare the second set of Chinese symbols to the first set, thereby allowing him to identify symbols by their shapes. A third set of Chinese writing (the “questions”), along with rules in English, is delivered to him. The rules lay out how Searle can provide the correct Chinese symbols needed to answer these questions through a comparison of the “script” and the “story”. He explains that he could become so proficient at computing using this method that his answers would seem like they were written by a fluent Chinese speaker, even though he cannot read, write, or speak a word of Chinese (352b-353a¶5).

    As children read they use several strategies that allow them to consider information from different sources to construct meaning. These sources of information are broken into three groups known as the cueing systems. These cue systems are semantic, language, and graphophonic. Semantic Information signifies the meanings in the text and in the mind of the reader. It includes word meanings, subject-specific vocabulary, figurative language and meanings presented in images (G. Winch, p32 2010)".
