Expert Solution & Answer
Chapter 1, Problem 17PS
Explanation of Solution
Chances of syntax errors between Pascal and Java while using semicolon:
Pascal uses semicolons to separate statements while JAVA uses semicolons to terminate statements.
- One of these approaches is more natural while the other is more error free syntactically.
- We personally feel that the Pascal approach is more natural as semicolons are used in English to separate different parts of a sentence.
- So, it should come naturally to an English speaker that a semicolon should be used to separate statements.
- So, this approach seems more natural. While the approach used by JAVA is less to prone to syntactic errors...

Although Algol60's flexible style permits statements to start and stop anywhere, the majority of programming languages today demand that statements explicitly end with an end symbol, such as a semicolon or a colon. In contrast, Python and a select few other programming languages have a predefined structure whereby statements start in a certain column and conclude at the end of a line of code unless continuation marks are included for each statement. You will discover how fixed or free formats affect readability, writability, and security in this section.
The phrases "cohesion" and "coupling" are used interchangeably in the area of computer programming.
Some programming languages—for example, Pascal—have used thesemicolon to separate statements, while Java uses it to terminatestatements. Which of these, in your opinion, is most natural and leastlikely to result in syntax errors? Support your answer.

- One characteristic of programming languages that varies widely from language to language is how parameters are passed. Among ALGOL, Pascal, Ada, C, C++, Java, and C#, no two languages pass parameters in exactly the same way.
