Case Study Programs in C
Dennis Ritchie was the first one who introduced the world to the C programming language around the fall of 1970. Despite its age, c programming still remains as the most preferred language when beginning to learn development. Its because it is super easy and versatile. People like it because its super easy and it is perfect for beginner who is looking for starting its programming journey. If anyone wants to be a pro in the programming world, he or she must start solving the case study problems and it can really improve their skills. In this tutorial, we will be basically learning why c programming is so important and how these case studies can help us up skill our programming game.
Understanding the concept
Before moving any further, we should discuss about what case study programs are? A case study program is basically the one that gives us the hypothetical situations which imitates the real-world scenarios. It acts as a catalyst agent because it helps the programmers to implement the theoretical knowledge that they have learned into real life situations. These case studies basically cover the different different parts of the programming languages such as data types, variables, constructors, arrays and several others. Usually, they play a crucial role in connecting mere concepts to practical knowledge.
Case study 1:
#include <stdio.h>
#include <string.h>
#define MAX_BOOKS 100
// Structure to represent a book
struct Book {
char title[50];
char author[50];
int year;
};
// Function prototypes
void addBook(struct Book library[], int *numBooks);
void displayBooks(struct Book library[], int numBooks);
void searchBook(struct Book library[], int numBooks, char searchTitle[]);
int main() {
struct Book library[MAX_BOOKS]; // Array to store books
int numBooks = 0; // Number of books in the library
int choice;
char searchTitle[50];
do {
// Display menu
printf("\nLibrary Management System\n");
printf("1. Add Book\n");
printf("2. Display Books\n");
printf("3. Search Book\n");
printf("4. Exit\n");
printf("Enter your choice: ");
scanf("%d", &choice);
switch (choice) {
case 1:
addBook(library, &numBooks);
break;
case 2:
displayBooks(library, numBooks);
break;
case 3:
printf("Enter the title to search: ");
scanf("%s", searchTitle);
searchBook(library, numBooks, searchTitle);
break;
case 4:
printf("Exiting the program. Goodbye!\n");
break;
default:
printf("Invalid choice. Please enter a valid option.\n");
}
} while (choice != 4);
return 0;
}
// Function to add a book to the library
void addBook(struct Book library[], int *numBooks) {
if (*numBooks < MAX_BOOKS) {
printf("Enter book title: ");
scanf("%s", library[*numBooks].title);
printf("Enter author name: ");
scanf("%s", library[*numBooks].author);
printf("Enter publication year: ");
scanf("%d", &library[*numBooks].year);
(*numBooks)++;
printf("Book added successfully!\n");
} else {
printf("Library is full. Cannot add more books.\n");
}
}
// Function to display all books in the library
void displayBooks(struct Book library[], int numBooks) {
if (numBooks == 0) {
printf("No books in the library.\n");
} else {
printf("Books in the library:\n");
for (int i = 0; i < numBooks; i++) {
printf("%d. Title: %s, Author: %s, Year: %d\n", i + 1, library[i].title, library[i].author, library[i].year);
}
}
}
// Function to search for a book by title
void searchBook(struct Book library[], int numBooks, char searchTitle[]) {
int found = 0;
for (int i = 0; i < numBooks; i++) {
if (strcmp(library[i].title, searchTitle) == 0) {
printf("Book found!\n");
printf("Title: %s, Author: %s, Year: %d\n", library[i].title, library[i].author, library[i].year);
found = 1;
break;
}
}
if (!found) {
printf("Book not found in the library.\n");
}
}
Output:
Benefits
- Application of Theoretical Knowledge
Case study programs helps us elevate our thinking and also our knowledge with simple programs that we use in our day-to-day life and helps us in building or knowledge.
- Problem-Solving Skills
They also contribute in the enhancement of logical learning as they immerse us in real life situations rather than just sticking up to the books and struggling. They are a great way to start learning.
Conclusion
Case study problems plays a vital role when it comes exploration of the language and development process. As it enables the visual transfer of the bookish knowledge into practical applications. Individuals commencing their programming journey should definitely start with this language as its super easy and fun to use and you can grasp the concepts at your own pace. This will help you up scale your knowledge and experience. It can really help them in improving their skills.
