Online C Compiler
Online C Compiler is a web-based tool powered by ACE code editor. This tool can be used to learn, build, run, test your programs. You can open the code from your local and continue to build using this IDE. Code and the output can be downloaded.
About C
C is a general purpose programming language, one of the powerful language that has inspired and influenced many other languages like Java, Python, Perl, Java, PHP, Ruby. C is widely used to build operating systemns and embedded system applications. Its origin is closely tied to the development of UNIX operating system. Compilers and Interpreter of many other programming languages are implemented using C. Its basic features and the control structures are directly and indirectly adopted by other programming languages.
C was originally developed at Bell Labs by Dennis Ritchie between 1972 and 1973. It was successor to the programming language B. Around 1980, C has become most widely used programming language. C provides contructs that maps the high level program to machine instrutions more efficiently which makes it one of the fastest in terms of code execution.

Possible reasons for Runtime Exceed error
- If your program is reading input from standard input and you forgot to provide input via stdin.
- Your program contains infinite loop, which may never break.
- Your program contains infinite recursive function calls.
- May be your program is trying to process large data and it takes much time to process

Cpp to exe converter online
To start your programming journey you first need to understand what compilers are. Compilers are the computer software that converts your high-level source code to executable machine-level instructions made up of 0s and 1s, that can be understood by the computer.
Compilers scan the high-level code line by line and show different kinds of errors present in the code in the command line.
Scaler Topics comes with a user-friendly IDE to compile, test, and run C++ programs online easily for free.
Working of the Online C++ Compiler (IDE)
Scaler Topics provides us with one of the best c++ compilers that is easily operated and that supports multiple programming languages.
Given below are some of the steps of our Compiler which users might find helpful:
The first step is your need to Sign-In to use the features of this compiler. It is possible to run your code without signing in but you will not have a track to your previous codes here, so it’s advisable to sign in to enjoy its cool features. Click on the button present at the top right corner and a window will appear.
- Code Editor: Write code in the code editor (which has syntax highlighting for more code readability). For users who are logged into the Scaler Topics Platform, the total number of characters in their code can go up to five thousand characters. For non Scaler Topics Users, their C++ code can have up to five hundred characters.
- RUN: In order to run a C program, a user can write C++ code in the editor and then click on the ‘RUN’ button after selecting the appropriate compiler version.
- SAVE: The C++ code written in the editor can be saved by clicking on the ‘SAVE’ button on the top right corner of the webpage. The saved codes can be accessed using the ‘MY SNIPPETS ’ button of the webpage.
- STDIN & STDOUT: In order to feed input to the C++ Code, users can use the Standard Input (stdin) console of our compiler and the output of the code appears on the Standard Output (stdout) of the compiler.
- SAVE: The programs saved can be made public — available for all — or private — accessible to only the code owner.
- FORK: Public code snippets can also be forked or downloaded in the ‘NEW’ section using the ‘FORK’ button. After forking a code, one can reuse it as per requirement.
- SHARE: Now that you have your code ready, you might need to share it with people. Our compiler also supports sharing of code in Read-Only Format. This can be done using the ‘SHARE’ button on the top right corner of the webpage.
Given below is a sample code snippet that adds two numbers in C++:
Learn C++ Programming
C++ is a programming language that allows programmers to write commands that can be understood by computers. It is a formal way of explaining the set of instructions to perform a particular task.
Why Learn C++?
C++ is one of the highly demanded programming languages by various tech giants. It has the following features:
- C++ allows writing programs that can be run quickly and that’s why it’s commonly used for developing complex game applications and business applications. For example, Google Chrome, Microsoft Office.
- It is easy to learn as it has simple code syntax that can be easily understood.
- It is an Object-Oriented programming language, i.e. it can visualize problems in terms of objects rather than in the form of procedures for solving them.
- It is a mid-level programming language.
- It has a lot of built-in libraries that help programmers in making development fast and efficient which saves time.
- C++ also supports dynamic memory allocation and memory management techniques.
C++ Syntax
C++ has various syntax rules that are scanned by IDEs. Following are some of the basic syntax that one should know to start their programming career in C++:
Loops (for loop, while loop, do-while loop)
Loops are used when there is the need to repeatedly execute a block of statements, for example printing the numbers from 1 to 5. Let’s execute this using all the three loops in our Scaler Topics IDE.
Online C / C++ Compiler
Online CPP is a super fast and instant tool that allows you run the C / C++ programming laguages on the fly in your favourite browser without need to worry about the installation and setting up the programming environment in your system.
