Paper For Above Instructions
In contemporary programming, C and C++ are integral languages for developing technical software that demands efficiency and performance. This paper tackles several programming challenges centered around C and C++ programming concepts, including table generation, linked list manipulation, and sorting algorithms.
Creating a Table in C++
The first task involves creating a table in C++ based on user input. The program requires the user to input an odd integer that determines the width of the table. The table is constructed row by row. Each element of the table can be generated using a formula. For example, if the width is given as 9, the elements can be calculated based on the row number and the width. Here's a simplified way of creating such a table:
include
using namespace std;
int main() {
int width;
cout << "Width of the shape? (Enter odd number only): ";
cin >> width;
// Check if width is an odd number
if (width % 2 == 0) {
cout << "Please enter an odd number." << endl;
return 1;
}
for (int i = 1; i <= width; i++) {
for (int j = 1; j <= width; j++) {
cout << (i + j) << " ";
}
cout << endl;
}
return 0;
}
After constructing the table, the user is prompted to enter the row number for which they wish to calculate the sum. This can be implemented using a simple loop. The sum is computed by iterating through the specified row and accumulating the values. Here is an added section for that:
int row;
cout << "Enter row number to get sum: ";
cin >> row;
int sum = 0;
for (int j = 1; j <= width; j++) {
sum += (row + j);
}
cout << "Answer: Sum of row " << row << " is " << sum << endl;
Linked List Functions in C
Next, we need to work with linked lists in C. This includes creating a linked list, sorting it, and deleting specific nodes. We begin by defining the structure of a node:
struct node {
int data;
struct node* next;
};
To insert a node into a sorted linked list, we implement the 'sortedInsert' function. This function scans through the list to find the appropriate position for inserting a new node. The node's data is then placed at the correct position while maintaining the order:
void sortedInsert(struct node* headRef, struct node newNode) {
struct node* current;
if (headRef == NULL || (headRef)->data >= newNode->data) {
newNode->next = *headRef;
*headRef = newNode;
} else {
current = *headRef;
while (current->next != NULL && current->next->data < newNode->data) {
current = current->next;
}
newNode->next = current->next;
current->next = newNode;
}
}
The 'removeRedundant' function handles duplicate nodes. Utilizing a while loop, it traverses the list and checks adjacent elements to eliminate redundancy:
void removeRedundant(struct node* head) {
struct node* current = head;
struct node* next_node;
while (current != NULL && current->next != NULL) {
if (current->data == current->next->data) {
next_node = current->next;
current->next = current->next->next;
free(next_node);
} else {
current = current->next;
}
}
}
Deleting a Specific Node
To delete a specified node, we create a function that checks whether the first node contains the target value. If it does, the node is deleted. If not, we find a node that contains the value, while keeping track of its predecessor:
void deleteNode(struct node** headRef, int key) {
struct node temp = headRef, *prev = NULL;
if (temp != NULL && temp->data == key) {
*headRef = temp->next;
free(temp);
return;
}
while (temp != NULL && temp->data != key) {
prev = temp;
temp = temp->next;
}
if (temp == NULL) return;
prev->next = temp->next;
free(temp);
}
Sorting Numbers with Bubble Sort
For sorting, we utilize a bubble sort algorithm. The function takes an array as input and sorts it in ascending order:
void bubbleSort(int arr[], int n) {
for (int i = 0; i < n-1; i++) {
for (int j = 0; j < n-i-1; j++) {
if (arr[j] > arr[j+1]) {
int temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}
}
The time complexity of this algorithm for the worst case is O(n^2), where n is the number of elements to sort. This occurs when the input array is in reverse order. To improve performance, we might consider another algorithm like merge sort, which generally has a better average time complexity of O(n log n).
Conclusion
In conclusion, proficiency in C and C++ is foundational for developing technical software. By mastering table creation, linked list manipulations, and optimal sorting techniques, developers can ensure efficient and effective software solutions. Each programming task enhances technical capabilities and supports algorithmic thinking—skills fundamental to any computer scientist.
