Problem Sets
1. What features of FORTRAN IV do you think would have had the greatest influence on Java if the Java designers had been familiar with FORTRAN?
– The logical loop control statement, and an “if” statement with optional “else” statement clause.
6. Make an educated guess as to the most common syntax error in C programs.
– The most common mistake is probably the lack of a semicolon (;) and the closing bracket of a statement (}).
8. Describe in detail the two most important reasons, in your opinion, why Speedcoding did not become a very widely used language.
– In my own opinion, it is mainly because the fact that Speedcoding took a lot of space on the disc, therefore make it ineffective.
13. What is the primary reason why C became more widely used than Fortran?
– Mainly because C is faster than Fortran, and probably because C is more readable too.
15. Are there any non procedural programming languages other than Prolog?
– Yes, four languages: Fortran, C++, COBOL, ALGOL.
16. What is your opinion of the argument that languages that are too complex are too dangerous to use, and we should therefore keep all languages small and simple?
– I think it’s up to the programmer they want to use a simple or a complex, but many will choose simple because it is more readable and more easy to spot a mistake.
25. Give a brief general description of the Java servlet.
– Java servlet is a Java programming language class used to extend the capabilities of a server. Eventhought servlets can be used to respond any types of requests, they are more commonly used to extend the applications hosted by web servers, so they can be thought of as Java Applets that run on servers instead of on web browsers.
