Learn how to program c


















Part 2. Understand the function of variables. Variables allow you to store data, either from computations in the program or from user input. Variables need to be defined before you can use them, and there are several types to choose from. Some of the more common variable types include int , char , and float. Each one stores a different type of data. Learn how variables are declared. Variables need to be established, or "declared", before they can be used by the program.

You declare a variable by entering the data type followed by the variable's name. For example, the following are all valid variable declarations: float x ; char name ; int a , b , c , d ;. Know where to declare variables. If you try to declare a variable later in the block, the program will not function correctly. Use variables to store user input. Now that you know the basics of how variables work, you can write a simple program that will store the user's input.

You will be using another function in the program, called scanf. This function searches the input that is provided for specific values. Manipulate your variables. You can use mathematical expressions to manipulate the data that you have stored in your variables. Part 3. Understand the basics of conditional statements. Conditional statements are what drive most programs.

The most basic of the statements is the if statement. TRUE statements always end up equaling a nonzero number. When you perform comparisons, if the result is TRUE then a "1" is returned. Understanding this will help you see how IF statements are processed. Learn the basic conditional operators. Conditional statements revolve around the use of mathematical operators that compare values. The following list contains the most commonly used conditional operators.

Write a basic IF statement. You can use IF statements to determine what the program should do next after the statement is evaluated.

You can combine it with other conditional statements later to create powerful multiple options, but for now write a simple one to get used to them. See the example program below to see how they interact. Part 4. Understand how loops work. Loops are one of the most important aspects of programming, as they allow you to repeat blocks of code until specific conditions are met.

This can make repeating actions very easy to implement, and keeps you from having to write new conditional statements each time you want something to happen. Use a FOR loop.

This is the most common and useful loop type. It will continue running the function until the conditions set in the FOR loop are met. FOR loops require three conditions: initializing the variable, the condition to be met, and the way the variable is updated. If you don't need all of these conditions, you will still need to leave a blank space with a semicolon, otherwise the loop will run forever. They only have one condition, and the loop acts as long as that condition is true.

You do not need to initialize or update the variable, though you can do that in the main body of the loop. Use a DO. WHILE loop. This loop is very useful for loops that you want to ensure run at least once. WHILE loops check conditions at the end of the loop, ensuring that the loop executes at least once. Part 5. Understand the basics of functions. Functions are self-contained blocks of code that can be called upon by other parts of the program. They make it very easy to repeat code, and they help make the program simpler to read and change.

Functions can include all of the previously-covered techniques learned in this article, and even other functions. The main line at the beginning of all of the above examples is a function, as is getchar Functions are essential to efficient and easy-to-read code.

Make good use of functions to streamline your program. Start with an outline. Functions are best created when you outline what you want it to accomplish before you begin the actual coding. For example, to create a function that adds two numbers: int add int x , int y ;. Add the function to a program. You can use the outline to create a program that takes two integers that the user enters and then adds them together.

The program will define how the "add" function works and use it to manipulate the input numbers. Part 6. Find a few C programming books. This article covers the basics, but it only scratches the surface of C programming and all the associated knowledge.

A good reference book will help you solve problems and save you from a lot of headaches down the road.

Join some communities. This article discusses how to learn the programming language of your choice and the correct way to begin your programming journey. So let us get started!

Before we begin reading further let me remind you that you have chosen a path that demands patience and motivation to never give up in spite of the challenge on the way. Read through and follow the steps below to become a programmer. The first and foremost step is to choose the language to learn. It is recommended to start with Python as it is simple like English and so easy to learn you can check out some of the best Python tutorial and get started. But you may choose the language that interests you and also based on the project that you would like to develop in the future.

So if you plan to develop a mobile app you may want to begin with Java or Kotlin for Android and Swift for iOS, and if you want to build a website Javascript is suggested, to begin with. Websites like Codecademy and Freecodecamp are recommended for interactive coding sessions. These were built with the idea that many beginners are stuck at the beginning when they start to learn to code while setting up the development environment.

These websites offer online text editors and compilers to begin coding instantly. If you are a person who likes a detailed study with step by step guidance then we recommend you enroll into any online programming tutorial that teaches you from the beginning to install and download the required IDE to basic concepts of the language and it ends with a capstone project to test your coding skills.

Some tutorials and courses also offer certifications that could help you later when you look for the job. We recommend Pluralsight and Lynda for searching the beginner tutorials for the preferred language. You may also want to check out some top-rated tutorials at Hackr. It is always suggested to make your fundamentals strong so as to be a pro coder. Learn the basics thoroughly and try your hands on the code by making your own problems and solving them.

Stress on the following topics to begin learning as they are common in almost all the languages. Building your personal project is the best way to analyze and learn what you have learned. Building a project of your choice would give you practical learning experience of the language in much detail as you would come across the implementation of the concepts that you have learned earlier and also learn how to deploy the project to be used by you and all others.

Moreover, as you build your projects add it to your profile or your GitHub account, this would help you in the future when you look for a job in development.

This is where most people get stuck at the deciding stage so what to build? The solution is simple. Let us see it below:. Whether it comes to studying or coding you must do what interests you the most.

You must enjoy the project area you choose so that you are passionate about it and it keeps you engage until built. If you choose something that is not of your interest you may end up giving up your project in the middle as you might eventually lack interest in it. So choose something that keeps you held upon itself like if like playing games then you might just want to develop a video game of your choice. Similarly, if you like photography you might want to build up your portfolio website showcasing your work or if you are someone who is interested in trading you might design an app or website to analyze your stock charts.

Analyze and give it a thought that what you like before you begin to build. Being confident about your capabilities is good but being overconfident is not. So it is recommended that you begin with simple and easy projects to explore the language more before you dive into building complex projects. For example, if you choose to build a video game do not straightaway begin with the complex video game League of Legends instead begin within something like tic-tac-toe or if you want to build a website do not start with building something like Amazon or Facebook instead go for something easier like a to-do list.

Be innovative and build something that is useful for you as well as that interests the community. If you are puzzled about where, to begin with, we have got you few ideas to start with your project building. You could begin with a simple website like making a to-do list or if you want to make a game app then games like Tetris, sudoku, and the flappy bird are good to start with learning programming.

If you want something challenging you might want to consider building a website similar to Twitter but with not as many features as Twitter offers but with some basic functionality like to tweet and follow.

Hackr gives you many project ideas for several languages ranging from the beginner level to the advanced level. C programming language is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain. I will list down some of the key advantages of learning C Programming:.

Just to give you a little excitement about C programming , I'm going to give you a small conventional C Programming Hello World program, You can try it using Demo link. C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language.
