Programming Concepts Assignment - St. Patrick's College (PRC)

This document presents a comprehensive solution to a Programming Concepts assignment, focusing on Java programming. It covers fundamental concepts such as data types (variables, constants), input/output operations, and operators. The assignment delves into control structures, including selection (if and switch statements) and iteration (for, while, and do-while loops), demonstrating their application in various programming scenarios. It further explores modularization using functions and procedures, emphasizing the scope and lifetime of variables and data passing between modules. The assignment also encompasses the use of arrays, program documentation (user and program documentation), and testing methodologies, including error detection (semantic and syntax errors), test plan creation, and the application of test data to identify logic errors. The solution includes Java code examples and explanations for each task, addressing the assessment criteria related to designing and developing code, using modularization, producing documentation, and applying test schedules.

Assignment Tasks

Task 1. Task Number
Pre-defined data types and input/output in Java 1 of 3
Aim of the Task
This task will assess your understanding of pre-defined data types in Java, your familiarity with input/output
mechanisms by writing program code using pre-defined data types, taking input from the user and
producing outputs.
Learning Outcome(s) of the Task
a) Identify and select appropriate pre-defined data types (1.1)
b) Use simple input/output and appropriate operators with the above (1.2)
Questions:
Give BRIEF answers to the following:
1. Define the following programming terms: variable, constant, data type.
2. How is a String variable different from char variable?
3. What is the difference between short int and long int data types?
4. Describe the process of declaring a variable. How is it done and what happens when declaration
code is executed?
Write the following Programs:
5. Write a Java program to perform basic arithmetic operations (addition and subtraction) on two
numbers. Numbers are assumed to be integers and will be entered by the user.
6. Write a program that prompts a user to enter a number for the radius of a circle, then computes the
area and circumference of the circle. Formula Area= π r², circumference = 2* π r.
7. Asks the user to enter studentID, Name, Sex, Age, and Height in meters; Stores these in variables of
appropriate data types and presents them together to the user. e.g.
StudentID:p1001215
Name: James
Sex: M
Age: 25
Height: 1.75 meters

Task 2. Task Number
Iteration Statements, Control Statement 2 of 3
Aim of the Task
This task will assess your understand of iteration/Loop and selection statements and demonstrate an
understanding by describing code structures and writing program code.
Learning Outcome(s) of the Task
a) Identify and use appropriate selection structures and loop structures for the given task (1.3)
b) Produce programs to desired standards (1.4)
c) Demonstrate the effect of scope and life-time of variables (2.2)
d) Pass data effectively between modules (2.3)

Tasks 3

Student Grades
Each Unit will be graded as a Pass, Merit, Distinction, Referred or Withheld
A Pass is awarded for the achievement of all Learning Outcomes against the specified Assessment
Criteria.
A Merit or Distinction is awarded for higher level achievement.
If all Learning Outcomes have not been achieved the work is Referred
Where there is some doubt or concern regarding the origin of some of the content, the work is
withheld. The student will then be interviewed to ascertain originality.
When a Unit has been assessed Grades are reported on the Online E - Learning System. Students can
obtain the grade awarded by viewing the Submission Inbox.
Grades are reported according to the following;
50% indicates Pass
60% indicates Merit
70% indicates Distinction
30% indicates Referred
5% indicates Unreasonable Submission
0% indicates Withheld
A percentage mark within one of the boundaries indicates further work would be required to achieve
the next highest grade e.g. 50% indicates that a Pass has been achieved, with additional work (according
to the grade descriptors) a Merit could have been achieved.
By viewing the Report the Originality can be obtained.
