1. What is meant by the concept of management myths.

2. Explain the incremental model with respect to its features, advantages and disadvantages.

1.   Assume that you are a software engineer. A client is asking you to develop a mobile application to manage the data in his mobile, with an advanced feature such as accepting voice as an input. However he still needs your help to identify other possible features. What is the most suitable process model?

2.   Mr. X wants an integrated Information System for his Car Company. He knows that the scope of the system is huge but wants it as soon as possible. He is willing to pay for the software for as long as all the subsystems are complete and delivered on time. If you are the software engineer, what process model will you use?

C++ EXERCISES

(a) Given int a = 5, b = 2, c = 4, and d = 5; determine the value of the expression:

d % b * c > 5 || c % b * d < 7.   

(b) Which repetition statement is preferred for user data input and its validation?             

(c) Write a for statement to populate an array, double val[NUMCOUNT], for the following case: Use a counter named double count that has an initial value of 16.2, a final value of 0.4, and a decrement of 0.2 and populate the val[] array with the value of count.

What is the size, NUMCOUNT, of the array val[]?

Write an if statement that uses the turtle graphics library to determine whether the turtle’s pen color is red or blue. If so, set the pen size to 5 pixels.

Python.

In most organizations, a long list of “to-do” projects for development exists. Since each organization only has limited staff and financial resources to accomplish the long list of IT project it is important to know how to identify, classify and select which projects will be undertaken.

Describe what occurs during project identification, classification and selection. Why can this process be challenging at times?

IN JAVA

Lab 10

This program reads times of runners in a race from a file and puts them into an array. It then displays how many people ran the race, it lists all of the times, and if finds the average time and the fastest time.

In BlueJ create a project called Lab10

• Create a class called Main
• Delete what is in the class you created and copy the Main class below into the file.
• There are 7 parts of the program that you will have to code. They are labeled Part A through Part G in the comments in the code.
• The comments for each part will describe the code you are to write.
• Using notepad, create the two data files given below and save them in the project folder on the hard drive
• There is also output given below.
• When finished, submit main to Zybooks

1.Read from a file that contains a paragraph of words. Put all the words in an array, put the valid words (words that have only letters) in a second array, and put the invalid words in a third array. Sort the array of valid words using Selection Sort. Create a GUI to display the arrays using a GridLayout with one row and three columns. 

2.The input file Each 
line of the input file will contain a sentence with words separated by one space. Read a line from the file and use a StringTokenizer to extract the words from the line. An example of the input file would be: 

Mary had a little lamb
whose fl33ce was white as sn0w
And everywhere that @Mary went
the 1amb was sure to go. 

3.You should have two files to submit for this project: 
Project1.java 
WordGUI.java

4. simple Java project

5. All variables have descriptive names or comments describing their purpose.

write a bash shell script using the for-loop construct that counts the number of files and directories looping through the files in the directory name provided by the user on a prompt by the script and prints "TOO many files" is the count of files is larger than a random number it generates between 20 and 40
