Write a program in ‘C’ language to accept a paragraph of text as input.
Make a list of words and the number of occurrences of each word in the paragraph
as output.
As part of the processing, an array and structure should be created wherein
each structure consists of two fields, namely, one for storing the word and
the other for storing the number of occurrences of that word.
#include<stdio.h>
#include<conio.h>
struct paragraph
{
char words[15];
int occ;
}p[50];
void main()
{
int i=0,j=0,k=0,flag=0;
char w[15],ch=0;

Bcsl 033 data and file structures lab s2-1Dr. Loganathan R This C program accepts student enrollment numbers, names, and aggregate marks. It ranks the students based on their marks, with the highest marks earning rank 1. The program then prints the enrollment number, name, mark, and rank of each student in ascending order of rank.
Bcsl 033 data and file structures lab s2-2
Bcsl 033 data and file structures lab s2-2Dr. Loganathan R This program multiplies two sparse matrices in C. It takes in two matrices from the user and converts them to sparse form by removing all zero values and storing the row, column, and value of non-zero elements. It then performs the multiplication by iterating through each non-zero element in the first matrix and matching columns with row elements in the second matrix, summing the products of the values at matched indices into the result matrix. Finally, it prints out the sparse and result matrices.

Bcsl 033 data and file structures lab s5-3Dr. Loganathan R This C program defines functions to add numbers to a queue and display the numbers in reverse order. The add() function takes user input of up to 5 numbers and stores them in an array. The display() function prints the numbers from the end of the array to the beginning to reverse the order, with front and rear pointers used to track the start and end of the queue. The main() function calls add() to populate the queue, then calls display() to print the numbers in reversed order.

The role of wall art in interior designing
The role of wall art in interior designingmeghaark2110 Wall patterns are designs or motifs applied directly to the wall using paint, wallpaper, or decals. These patterns can be geometric, floral, abstract, or textured, and they add depth, rhythm, and visual interest to a space.
Wall art and wall patterns are not merely decorative elements, but powerful tools in shaping the identity, mood, and functionality of interior spaces. They serve as visual expressions of personality, culture, and creativity, transforming blank and lifeless walls into vibrant storytelling surfaces. Wall art, whether abstract, realistic, or symbolic, adds emotional depth and aesthetic richness to a room, while wall patterns contribute to structure, rhythm, and continuity in design. Together, they enhance the visual experience, making spaces feel more complete, welcoming, and engaging. In modern interior design, the thoughtful integration of wall art and patterns plays a crucial role in creating environments that are not only beautiful but also meaningful and memorable. As lifestyles evolve, so too does the art of wall decor—encouraging innovation, sustainability, and personalized expression within our living and working spaces.
