Hi please assist
thanks Computer Science question
Step by step
Solved in 2 steps
- Java Assignment: Experiment with naming rules in Java Does the language use static or dynamic scoping? Can scopes nest? Are they open or closed? Does the scope of a name encompass the entire block in which it is declared, or only the portion after the declaration? How does one declare mutually recursive types or subroutines? Can subroutines be passed as parameters, returned from functions, or stored in variables? If so, when are referencing environments bound? Justify your answers with suitable code snippet and its output.Please answer true or false for JAVA problem below: The communication activities directly related to data input and output should be placed in the data definition class.Why do modern programming languages need to support both value and reference passing? When deciding between these two alternatives, why is it so difficult to choose only one? Your solution should address both the positives of having both and the drawbacks of having either alone.
- What do you understand by function overloading explain with code in java programming.Program in JAVA and please show output and comment the program Introduction: This assignment is to provide practice in using the Java I/O techniques discussed in the Module 10 video lectures and readings. Although the main focus of this assignment is Java I/O techniques, Java design and implementation techniques discussed in earlier modules should be incorporated in to this assignment. Problem: Supplied is a data file from the US Census which contains data from US school districts and reports statistics related to child poverty (http://www.census.gov/did/www/saipe/data/highlights/2013.html). It is desired to have a summary report which calculate basic statistics at the state level. Desired Implementation:Java 8 implementation to read the supplied text data and produce a report similar to the below: There should be two separate “programs” (two separate .java files each with a main method), one to read the text data file and write a reformatted file to be read by the second program…Program in JAVA and please show output and comment the program Introduction: This assignment is to provide practice in using the Java I/O techniques discussed in the Module 10 video lectures and readings.

- Using a pointer as the return value is considered a poor practise in C. For example, how does dynamic memory allow us to return an object pointer from a function safely?Book : Peter Sestof - Programming Language Concept Page: 158 pdf Exercise 8.9 Extend the language and compiler to accept initialized declarations such as int i = j + 32; Doing this for local variables (inside functions) should not be too hard. For global ones it requires more changes.118. Prototyping model is based on a. limited functionality b. unlimited functionality c. linear combinations d. non linear sequential statements
- Bad pointers, writing past the limit of memory allotted, and memory leaks are the issues.When it comes to memory management, C++ offers a tonne of freedom.You can immediately work with pointers and allocate and deallocate memory.Freedom entails a price. You can make mistakes with reservations because the language lets you do so. The use of references and deallocation are both subject to error.What can you do to secure your code since C++ lacks built-in safety checks?Code for this in C: Implement a c program using the single-subscripted array and its operations with emphasis on the creation of programmer-defined data types and the use of separate files for the definition - .h, implementation - .c and client code - .c.Airline Reservation System A small airline has just purchased a computer for its new automated reservations system. The president has asked you to program the new system. You are to write a program to assign seats on each flight of the airline's only plane (capacity: 10 seats). Your program should display the following menu of alternatives: Please type 1 for "first class" Please type 2 for "economy" If the person types 1, then your program should assign a seat in the first class section (seats 1-5). If the person types 2, then your program should assign a seat in the economy section (seats 6-10). Your program should then print a boarding pass indicating the person's seat number and whether it is in the first class or economy section…The Issues: Bad pointers, writing to the end of allotted memory, and memory leaks are all possibilities.When it comes to memory management, C++ provides a great deal of freedom. You can allocate and deallocate memory as well as directly manage pointers. Flexibility comes at a price. Because the language permits you to allocate memory, you can make mistakes. Similarly, you may mess up deallocation and pointer usage.
