OBJECTIVES In this lab assignment, students will learn: How to declare one-dimensional and two-dimensional Arrays - How to save data in one-dimensional and two-dimensional Arrays How to use a for loop to iterate one-dimensional and two-dimensional Arrays How to access and retrieve data from one-dimensional and two-dimensional Arrays How to pass one-dimensional and two-dimensional Arrays to a function How to use parallel arrays - How to declare and use the c-string COURSE PREPARATION Read the following documents: • Chapter 8 of the lecture slides and textbook. CSC134-Coding Guidelines.doc posted in Course Resources -> Tutorials and Guidelines to Create and Submit C++ Programs. GRADING RUBRIC Indent code and insert comments to document your program. [10 pts] Program must be implemented and run as instructed. Program that does not compile and run will not receive any credit. [Programming Skills, 80 pts] Submit the C++ programs to Blackboard correctly. [10 pts] INSTRUCTIONS Develop a C++ program “YourLastname-Lab6" which reads data from the attached text file "job-salaries.txt", then performs the following data analytic tasks:
● ● • • ● Administrative Assistant 29000-56000 Software Engineer 61000-126000 Project Manager, (Unspecified Type / General) 49000-112000 Operations Manager 42000-103000 Office Manager 34000-69000 Financial Analyst 46000-81000 Software Developer 50000-104000 Customer Service Representative (CSR) 28000-54000 Senior Software Engineer 85000-156000 Executive Assistant 39000-79000 Do not use any non-constant global variables. All arrays should be parallel arrays, the specific job and its salary data should use the same index in all parallel arrays. Read all job titles and salary ranges from the data file and store the jobs and salary ranges into two arrays, the maximum number of jobs that can be processed by this program is 20. O Store job titles in a one-dimensional string type array jobs [20]. o Store low salary and high salary in a two-dimensional double type array salary Ranges [20][2]. Sample output Calculate the average salary for each job using averageSalary = (lowSalary + highSalary)/2.0, store the average salary in another one-dimensional array avgSalary[20]. Display the job title, low salary, high salary and average salary on the screen. Identify and display the lowest and highest average salary from the array avgSalary[ ]. Sort all jobs by average salary in ascending order and then display the sorted jobs with corresponding low salary, high salary and average salary. o You are required to define a function to perform the job sorting. This should be a void function. o o It requests all three arrays and number of jobs as parameters. o The code template below used selection sorting algorithm.
