Discuss why change is unavoidable in complex systems with examples of software process activities

that help predict changes and make the software under development more resilient to change

The class shown below keeps track of a pressure sensor in a laboratory. When a Sensor object is created using the first constructor, the initial pressure is set to zero. When it is created using the second constructor it is set to the value of the parameter. The pressure should not be set to a value less than zero. Therefore, if the input parameter to the setPressure method is a negative number, the pressure should not be changed and a value of false should be returned. If the pressure is set successfully, a value of true should be returned. (a) Write the code for the Sensor class. (b)

Write a C Program to calculate the Average of an array elements where the elements are received as input.

Write a C program to input number from user and check number is palindrome or not using while loop.

Looping a number and taking away each digit of it is so much fun, but I wanted to try out a much more complex task: getting the largest digit among them all.

Think you can handle the job?

Instructions:

1. Input a non-zero positive integer.
2. Using the same concept as the previous problem, figure out how to separate the digits of a number and determine which of the digits is the largest one, using a while. Afterwards, print the largest digit.
3. Tip #1: Create another variable that will hold the largest digit. Initial its value to a negative integer, like -1, outside the loop.
4. Tip #2: Everytime you get the rightmost digit, check if it is greater than the current largest digit. If it is, set it as the new largest digit.

Input

A line containing an integer.

214

Output

A line containing an integer.

4

Are Characters Created Equally?

1. What do you mean by Program? Briefly describe the basic structure of C programs.

2. What is a token? Differentiate between a for loop and a while loop? What are it uses? 

3. What is a data type? Differentiate between array and pointer. Write a program to interchange 2 variables without using the third one. 

4. What is an array of pointers? Is it possible to have negative index in an array? Why is it necessary to give the size of an array in an array declaration?  

5. Submit a Report "the impact of improving debugging skill on programming ability".

Make a class student. The student class has data members such a sroll number, name, branch. Create a class called exam that has data members roll number and six subject marks. Derive the result class from student and exam it has own data members such a total mark, and result. Write a Java program to model the relationships.

Create C++ full program that calculates the value of u. u=a+gv^2

Create and Implement a C++ program to make a class named Array_Operations

● Globally declare size of array.

● Data member of class should be a dynamic array.

● Set all values as zero in default constructor.

● Overload Subscript operator i.e. []

● Overload streams operators (should be friend functions)

o cin i.e. >> to input object values

o cout i.e. << to output/display values

● Now take 4 objects of class in main. Initialize values of 1st and 2nd array (using stream

operators >> and subscript [] overloading). Now overload +,-, operators to add and

subtract 1st and 2nd arrays and store the result in 3

rd and 4th array respectively. Now

display all arrays.
