How To Start C Programming In Windows 10

Compile and Run C Program

To compile and run a C language program, you demand a C compiler. A compiler is a software that is used to compile and execute programs. To gear up a C linguistic communication compiler in your Calculator/laptop, there are ii ways:

Download a total-fledged IDE similar Turbo C++ or Microsoft Visual C++ or DevC++, which comes along with a C language compiler.
Or, y'all tin use whatsoever text editor to edit the program files and download the C compiler separately so run the C plan using the command line.

If you lot oasis't already installed an IDE for the C language - Follow this step-by-step guide to Install Turbo C++ for C Language

Using an IDE - Turbo C

Nosotros will recommend you to use Turbo C or Turbo C++ IDE, which is the oldest IDE for C programming. It is freely available over the internet and is adept for a beginner.

Pace 1: Open turbo C IDE(Integrated Evolution Surroundings), click on File then click on New

Step ii: Write a Hello World program that we created in the previous article - C Hello World program.

Step 3: Click on Compile card and then on Compile option, or press the keys press Alt + F9 to compile the code.

Step 4: Click on Run or press Ctrl + F9 to run the lawmaking. Yes, C programs are get-go compiled to generate the object lawmaking and then that object code is Run.

Step 5: Output is here.

Run C Program Without using any IDE

If yous do non wish to set up an IDE and prefer the old school way, then download the C compiler which is called gcc from the GCC website https://gcc.gnu.org/install/

Once you accept downloaded and installed the gcc compiler, all you take to do is, open up any text editor, copy and paste the C programme lawmaking for C Hello World Plan, and relieve it with the proper noun the helloworld.c like any other file you save with a name.

Now, Open Control prompt or Last(if yous use Ubuntu or Mac Os), and become to the directory where you have saved the helloworld.c programme file.

Type the control gcc howdy.c to compile the code. This will compile the code, and if there are no errors and so it will produce an output file with proper noun a.out(default name)

Now, to run the plan, blazon in ./a.out and yous will see How-do-you-do, World displayed on your screen.

          $ gcc hi.c $ ./a.out

Hi, World

Difference between Compile and Run in C?

You must be thinking about why it is a 2 pace procedure, first, we compile the code then nosotros run the lawmaking. We did the same affair with Turbo C and the aforementioned is with the command line or Terminal as well.

Well, the compilation is the process where the compiler checks whether the program is correct syntax-wise, and there are no errors in the syntax, and if the code is fine converts the C linguistic communication source code into car understandable object code.

When we run a compiled program, it is just the already compiled code that is run.

This divergence is clear when nosotros run a C plan using the control line. When yous compile the code, a .out file is generated, which is then Run to execute the program.

Once a .out file is generated, and then y'all make any changes to your plan in the source code file, yous will have to again compile the code, otherwise, the .out file will have the old source code and will keep running the old programme itself.

Frequently Asked Questions(FAQ)

1. What do you understand by the procedure of compilation?

Information technology is a procedure where the compiler checks whether the plan is syntactically correct or not. If there is whatsoever fault found in the syntax then information technology will throw the errors. The fault thrown at the time of compilation is called a Compile-time error.

2. Name the keys used in Turbo C to compile the code.

ALT + F9 is used in turbo C in club to compile the code.

iii. How is a C program run?

During the compilation and execution of the C plan, the compiler generates output files with the same name equally that of the C program file but with different extensions. The .c extension file is called the source file that keeps the code of the program. Now, when we compile the file, then the C compiler looks for errors.

4. Where tin I write and run the C program?

You can utilize an IDE to write and run the C program by following these steps:

Step 1: Open turbo C IDE(Integrated Development Environment), click on File and so click on New.
Step 2: Write the C program code.
Step 3: Click on Compile or press Alt + F9 to compile the lawmaking.
Step 4: Click on Run or printing Ctrl + F9 to run the code.
Pace five: And turbo C will open the panel to show y'all the output of the program.

Determination

This tutorial was all most how to run and compile whatsoever C programme using an IDE proper noun Turbo C . We take also covered how it can be done without using any IDE.
