2. Ticketing and Reservation system

Our older generations will vouch for how tedious long distance travel would be prior to the digital era. Not only would the journey be long but also getting access to the modes of transport used to be rather painstaking. Long queues at the booking centers, which too would be situated fairly away from usual residential areas, a limited number of seats and the highly inefficient and painstakingly slow ticketing process would dampen the spirits of traveling.

With e-ticketing systems, access to air, rail, and bus journeys have not only increased considerably but also people can easily book tickets on their own without having to depend on middle persons and agents. As increasing numbers of booking platforms emerge with more tech savvy features, we have C programming to thank. The source code in C can be adopted to a seamless booking process for not only air, rail or bus tickets but also car rentals.

In fact, using the same codes and libraries, developers may also consider developing e-booking platforms for hotel bookings, restaurant tables and so much more. Strings and arrays in C programming are extremely helpful to ease out the booking window for both web and mobile phone users.

Further, if the developers strip external file storage from the source code, then the user data will also be erased once the ticket has been booked. This eliminates the fear of a data privacy breach for the users.

This system helps the users to easily check the book tickets, bus schedule, the bus status board, and cancel reservations. When buying tickets, the user should first enter the bus number. Subsequently, the system will show the entire number of bus seats and the passengers’ names. The user then needs to enter the seat number, the number of tickets, and the person’s name.

It is one of the fundamental C language projects for beginners that uses if-else logic, arrays, loop statements, and different functions like cancel(), login(), etc.  This C project helps you to simulate a bus reservation system. This system takes input like the number of seats, bus type, the price of each seat, luggage load, individual bags permitted per ticket, etc. 

These inputs help you to set up a reservation system wherein you will display a list of available seats, accept reservation requests, and process them. Subsequently, you can add more functionality like a refund, cancelling a reserved seat, bulk booking, etc. Moreover, it assists you to determine seat availability and search for the booking information. You can use SQLite DB for data storage or use simple file handling.

What makes C programming so popular?

As an all purpose programming language, C programming has a diverse range of usability. It entails upgraded attributes of Unix which has transformed the scripting of softwires for operating systems, databases and compilers among others. It is essentially the boon of C programming that Graphical User Interfaces and Integrated Development Environments have become a lived reality and enjoys the widespread application. 

With the advent of C programming, memory allocation and optimization became a lot easier. Developers gained a significant rise in the bandwidth to develop more high performing web applications using C programming. Naturally, the gamut of c projects are rather divergent.

Originally conceived as source code for Unix, C programming evolved into a standalone programming language which then resulted in most of the modern operating systems that are widely used these days like windows and iOs. The pivotal role that C programming has played in software development has earned it the title of “mother of all programming languages”.

Additionally, C programming is highly extendable and portable so a wide range of libraries can be stored which in turn enhance the functionalities of the various web applications that are scripted using C programming. The libraries of functions of C programming make it amenable to the implementation of numerous data types and other functions like loops, arrays, structures etc. 

Google’s MySQL, Chromium, Oracle, and most Adobe apps also use the C programming language extensively. Also, it performs a pivotal role in our everyday lives because most smart devices people use today are driven by C-programmed technology.

You can experience seamless flexibility when working on any of the C language projects. The flexibility can be perceived in terms of memory management and allocation. This is one of the prominent reasons why C is so widely used. Programmers own full control over how they allocate and reallocate memory. Consequently, it leads to better efficiency and optimization. Moreover, the C programming language offers various memory allocation and management functions, such as malloc(),calloc(), etc.

C is known as a mid-level language. It suggests that it owns the characteristics of both high-level as well as low-level languages. Therefore, it is straightforward to understand and use. Moreover, it assists users in collapsing a code into smaller, more readable parts since it is a structured programming language.

C is known as a structured programming language because it can disintegrate a program into smaller functions. Such functions also help you to reuse code. So it is easy to understand and work on.

When you work on several C language projects, you can understand its dynamic memory allocation, which means the allocation of memory at runtime. The allocated memory can be freed up anytime in the C language through pre-defined functions.

Another prominent reason for the wide popularity of C is that the compilation and execution occur fast in C. This is because there are fewer inbuilt functions and, therefore, a lesser overhead.

Why Code a Project in C?

Which industries commonly use C projects?

In today’s increasingly automated technological landscape, C projects have had an all encompassing utility. Chances are high that from the minute you wake up till when you head to bed, you’ve had a tryst with C programming at every step of the way. If you’re a smartphone user, the algorithm of your phone is likely to have its base on C programming. So right from the alarm clock that you wake up to to the last WhatApp message that you check before dozing off, it can all be traced back to C programming. 

Similarly, major computers operating systems be it Linux, Microsoft Windows or Mac have their kernels scripted in C programming. So chances are high that the PC that you work on also has its root in C language. Moving onto databases that actually form the rubrics for most customer applications, like Oracle, MySQL and several others, were designed in C and it wouldn’t be completely wrong to claim that almost every application that we use has one or the other imprint of C programming. 

Further, our contemporary lifestyle makes us dependent on a whole host of smart gadgets. The technology that drives these smart gadgets is the internet of things which to are programmed in C language. From sensor technology to artificial intelligence, C projects are everywhere. 

We will be discussing some unique project ideas in C here which developers, both established and aspiring, can consider building upon. Some of these projects already have their prototypes in practice and these can be looked upon as upgraded innovations while the others are novel ideas with a lot of merit to be developed into a workable project.

What doesn’t the C language support function overloading or polymorphism?

When the C code is compiled, the name of the symbols must remain intact with the machine code. When we add function overloading to our source code, we should also introduce some name mangling techniques so that the function name does not clash as a preventive measure. C language is not a strictly typed language as many things like data types are convertible. This overload can add complexity and confusion in a language like C. On the other hand, in C++, you get machine-generated names for the symbols in the compiled binary, which is why C++ has polymorphism and C doesn’t.

How are the Macros different from the functions or methods?

Macros are preprocessed, whereas functions are compiled with the source code. No type checks are done in the case of macros, whereas type checking is done in the case of functions. Using macros increases the length of code, whereas functions keep the size of source code unaffected. Speed of execution is faster in macros as compared to the functions. Before the source code is compiled, the macro name is replaced by the macro value, whereas in functions, the transfer of control occurs during the function call. Macros are only helpful when you have minimal code to reuse; otherwise, functions are considered a better choice. Macros don’t check any compile-time errors, whereas functions do.

How is a call by reference different from a call by value?

In C language, functions can be invoked in two ways: Call by value and Call by reference. The values commonly differentiate them, which are passed to them as parameters. When we call a function and pass values of variables as the parameters to that function, such calls are called call-by values. And when we call a function by the address of actual variables as parameters to that function, it is called call by reference. In a call by value, the changes made to the values do not affect the variables, whereas, in a call by reference, the actual variables get affected.

What games can you make with C?

You can create various games in C, including Tic-Tac-Toe, Snake, Hangman, Minesweeper, Pong, a basic text-based RPG, and even a simple Sudoku solver, leveraging arrays, loops, and game logic.

Is C language tough?

The C language can be challenging due to its low-level operations, manual memory management, and lack of built-in safety features. However, mastering it provides a solid foundation for understanding more complex programming concepts.
