Why should a system administrator log in to a computer running a GUI environment as his/herself and then switch to the administrator account instead of logging in directly as the administrator? Solution In most of the cases system administrator must log in to a computers mostly with windows because it os required so that he/she can log in in to the GUI as root. other than the windows means unlike windows you cannot reboot this point to start using the system. From there you will be taken to the administrator account by using the existing account by using the administrator..

Create a C program which auto-completes suggestions when beginning to type a command and pressing tab. The program needs to read all the files names in a directory given by the user and store them in a data structure made up of a 26-element array of linked lists. A linked list implementation in C is required. Create a linked list for each letter of the alphabet in which you\'ll store the filenames which begin with that letter in some order. After reading the filenames, the user provides the beginning of a filename they\'ll like to search. The output should be all the filenames which match that prefix. The program should continue to ask for beginnings of filenames until an empty string is entered. Solution Code ----------- #include #include #include struct node { char data[10] ; struct node *next; }*head; node* arrNode[26]; char lettersPosition[26] = {\'a\',\'b\',\'c\',\'d\',\'e\',\'f\',\'g\',\'h\',\'i\',\'j\',\'k\',\'l\',\'m\',\'n\',\'o\',\'p\',\'q\',\'r\',\'s\',\'t\',\'u\',\'v\',\'w\',\'x \',\'y\',\'z\'}; /* * Creating Node */ node* create_node(char fileName[]) { node* newnode = (node *)malloc(sizeof(node)); if (newnode == NULL) { printf(\"\ Memory was not allocated\"); return 0; } else { strcpy(newnode->data,fileName); newnode->next = NULL; return newnode; } } void display(struct node *r) { r=head; if(r==NULL) { return; } while(r!=NULL) { printf(\"%s \",r->data); r=r->next; } printf(\"\ \"); } void search(char beginningFilePrefix[]) { node* newnode = NULL; char str[10]; strcpy(str,beginningFilePrefix); char dirPos = str[0]; node* r = arrNode[lettersPosition[dirPos]]; if(r==NULL){ printf( \"No file is avialable in directory\"); return; }else{ while(r!=NULL){ char tempFile[10]; bool isMathched = true; strcpy(tempFile,r->data); for( int i = 0; i < 1 ; i++){ printf(\"%c %c\",str[i],tempFile[i]); if(!(str[i] == tempFile[i])){ isMathched = false; } } if(isMathched){ if(newnode == NULL){ newnode = (node *)malloc(sizeof(node)); strcpy(newnode->data,r->data); }else{ struct node *temp,*right; temp= (struct node *)malloc(sizeof(struct node)); strcpy(temp->data,r->data); right=(struct node *)newnode; while(right->next != NULL){ right=right->next; } right->next =temp; right=temp; right->next=NULL; } } r=r->next; } } if(newnode==NULL){ printf(\"File not found with given search critieria\"); }else{ printf(\" Below are the output or file list which are matched with search criteria \ \"); while(newnode!=NULL){ printf(\"%s \ \",newnode->data); newnode=newnode->next; } } printf(\"\ \"); } void displayFromArray(int dirPosition) { node* r= arrNode[dirPosition]; if(r==NULL){ printf( \"r is null\"); return; } while(r!=NULL){ printf(\"%s \",r->data); r=r->next; } printf(\"\ \"); } void insertIntoArray(char fileName[],int dirPosition){ struct node *temp; temp=(struct node *)malloc(sizeof(struct node)); strcpy(temp->data,fileName); node* r = arrNode[dirPosition]; if(lettersPosition[dirPosition] == fileName[0]){ printf(\"directory starts with letter %c cannot hold fi.

How do you center text within a label? Solution Form: The form of a piece is its form, including its volume or perceived volume. A three-dimensional artwork has depth as well as breadth and height. Three-dimensional form is the basis of sculpture.However, two-dimensional artwork will win the illusion of type with the employment of perspective and/or shading or modelling techniques. Formalism is the analysis of works by their form or shapes in humanities or anthropology. Line Lines and curves are marks that span a distance between 2 points . As an component of visual art, line is the use of assorted marks, outlines, and implied lines in design and style. A line has a width, direction, and length. A line\'s width is typically referred to as its \"thickness\". Lines are typically referred to as \"strokes\", especially once referring to lines in digital design. Color Color is the element of art that\'s made once light-weight, striking AN object, is reflected back to the eye. There are 3 properties to color. The first is hue, which merely means that the name we have a tendency to offer to a color . The second element is intensity, which refers to the vividness of the color. A color\'s intensity is sometimes stated as its \"colorfulness\", its \"saturation\", its \"purity\" or its \"strength\".The third and final property of color is its value, meaning however light-weight or dark it is. The terms shade and tint refer to value changes in colours. In painting, shades are created by adding black to a color, while tints ar created by adding white to a color..

a) How can habitat selection and sexual selection drive sympatric speciation? b) What are hybrid zones and why can they be viewed as “natural laboratories” in which to study speciation? Solution a)sympatric speciation is when a small population becomes a new species without geographic separation due to reduced gene flow by factors like polyploidy, habitat differentiation, and sexual selection.This type of speciation takes place in geographically overlapping populations.There is no physical barrier, but still interruption of gene flow is there. For example in fruit flies, food source (habitat selection) and apple maget fruit flies Ex. Cichlids(Differ in coloration of breeding males). Mate choice based on male breeding coloration is the main reproductive barrier that normally keeps these gene pools of these two species separate. b)Hybrid zones are regions in which members of different species meet and mate, producing some offspring of mixed ancestry. Such regions are \"natural laboratories\" in which to study speciation because scientists can directly observe factors that cause (or fail to cause) reproductive isolation..

What are some advantages and disadvantages of using a doubly linked list versus a linked list? Solution The advantages and disadvantages of using a doubly linked list versus a linked list: -> It is easy to operate on many operations because double linked list offers easy implementation. whereas the linked list has to be required more data for the same operation. -> A double linked list can bisect in both directions whereas linked list bisect only in one direction. -> One of the disadvantage of double linked list is it occupies more space so that more operations are required when compared to a linked list of the same operation. -> Insertion and deletion takes more time in double linked list when compared to linked list because in the double linked list more pointer operations are required..

What motivated so many Americans to fight and kill one another in the long and bloody American Civil War? What did they believe they were fighting for? Solution There were several reasons for the civil war: 1. Abolition of slavery - The people in the south were mostly plantation farm owners which is a labour intensive work. So, when Abrahim Lincoln decided to abolish slavery, it was seen as a direct attack on their way of life. They did not want to be dictated terms by the people from the north who were mostly business owners and the northerners did not support slavery. 2. Union over State powers - In the decision to create policies such as abolition of slavery, the states had no individual power to decide if it supported or opposed the idea. This made the southern states feel threatened by the power of the union over them which they were not accustomed to prior to 1789. 3. Denial of request of secession - Some states in the south wanted to secede from the United States but the then president Abrahim Lincoln refused to entertain this idea. This riled up the people in the south even further. The Northerners believed to be fighting for the abolition of slavery as well as uniting the nation under a single rule of the union. On the other hand, the southerners believed to be fighting for their way of life and seceding from the rest of the United States..

Using examples, discuss the main determinants of migration. Solution Broadly migration factors can be divided into– 1. Economic factor: The push factor for these citizens can be poverty, low wages and unemployment. For e.g. Often those who migrate from poorer countries like African and South Asian countries face severe economic hardships. They’re pulled by factors like higher wages and better standard of living. 2. Political factor: Civil unrest and war can lead to many citizens becoming refugees as it leads to massive loss of life and property in a country. This becomes a natural factor due to which people migrate to politically stable countries. For e.g. The recent war in Syria has pushed Syrian to migrate to Europe and other developed countries. 3. Socio-cultural factors: Often discrimination based on ethnicity, religion or color can also result in migration to other countries. Ethnic cleansing in African countries has been one of the reasons why Africans moved to nearby countries where they felt safe..
