Online C Compiler

We must first grasp what compilers are if we want to begin our coding journey. Compilers are the software system that transforms our high-level source code into Machine Level instructions. Machine Level codes can be executed and interpreted by a computer.

The high-level code is line by line scanned by compilers. The compiler shows various types of errors at the command line. A code without error is executed correctly.

A compiler mainly performs the following function:

  • Reading the files,
  • Examining the code and
  • Solving the code into a format.

The Online C compiler supports the C Language as the source programming language. Compilers are pretty complex programs with features like Error Checking.

An online C compiler must ensure that the output code's logic always matches the input code. It makes sure that nothing is lost during conversion. In the most strict sense, an online C compiler is a translator. It ensures that the output is accurate and maintains the original logic.

Coding ninjas provide a quick and easy Online Compiler. From any location, you can instantly log in and get to work. One can easily access our online c compiler. You can quickly write and run C code online, thanks to Codestudio's friendly online c program compiler.

Our C Compiler gives an excellent online IDE for C programs. The best online C compiler is what we've worked to produce.

Working of the Online C Compiler

The online C compilers work in various stages for analysing source code to output code. Despite their variations, they usually perform the below actions:

Lexical Analyser: The online C compiler separates the source code into lexemes. Lexemes are individual pieces of code. It represents specific coding patterns.

Syntax Analyser: The online C compiler checks the syntax of the code. Checking is done based on the rules for the source code. This method is also known as parsing.

Semantic Analyser: The logic of the code is tested by the online C compiler for accuracy. By verifying the accuracy of the code, this phase extends beyond syntax analysis.

Intermediate Code Generation: After the code has gone through all three analysis methods, the online C compiler creates an IR code of the source code.

Optimisation: The online C compiler optimises the IR code. Then the compiler will determine the kind and degree of optimization and generate the output code.

Output Generation: The online C compiler creates the final output code. Using the optimised IR code.

To access the abilities of our online c compiler, you must first Sign in. Our online c compiler works in the following ways:

Code Editor: Use the code editor to enter code. You can modify code easily. Syntax highlighting is available for high readability.

RUN: After entering C code in the editor and choosing the correct compiler version. Users can click the "RUN CODE" button and run their C program.

Reset Code: To reset the C code entered into the editor. Click the "reset" button in the top right corner of the editor.

STDIN & STDOUT: Users can utilise our compiler's Standard Input (stdin) console to feed input to the C Code. And the Standard Output (stdout) of the compiler displays the output of the code.

Benefits of using Online C Compiler

Some of the benefits of using an online c compiler are as follows:

  • Enhanced performance.
  • No Setup is needed.
  • We can access it from anywhere.
  • Decrease in system load.
  • Source code and program protection.
  • Increased output and accuracy.
  • Compile time portability of programs.

How to write a C program?

We will start with an example of C programming:

#include <stdio.h>
int main()
/* The main function*/
    printf("Welcome to Coding Ninjas!!");
    return 0;

Now, Let's understand this program:

Comment: Start your comment with "/*" and end it with "*/." Although using comments is not required. It is still a good practice. It makes the code easier to read.

Include Section: Several keywords, statements, and functions, like printf(), scanf(), and others, are used while writing programs. The program must contain the file having the definitions of these functions. We used stdio.h in the program shown above.

Display statements: The code above uses the printf function. Anything we enter within double quotes prints precisely as it appears on the terminal.

Function Main(): It is the initial step in any C program. This function starts the execution of the C source code.

Return type: Whether your software has successfully compiled or not should be known to the compiler. This is determined by examining the return value of the main function (). We have a return 0 statement at the end of the main function. It is assumed there is a problem unless the return value is 0.

How to compile and run the c programs online?

Online C compilers are websites where you may create your code. Then we send it to a server that already has an inbuilt compiler. As a response, the result is obtained and rendered on the client side.

The C code can be easily compiled using the codestudio's online c compiler. Enter the code in the editor and press "RUN CODE." Then the program will run and be compiled. The output is shown on the standard output console.
