It provides you with a platform for writing, compiling, and executing C++ code directly from your web browsers without needing local installation of development tools like compilers or IDEs. It is designed in such a way that it will help both beginners and seasoned programmers thus facilitating a deeper understanding of low-level programming and algorithmic logic.

About C++

C++ is an object-oriented, case-sensitive, free-form programming language that is an extension of C programming. It is a mid-level programming language that encapsulates the features of both low-level and high-level languages.

Its versatility and performance make it a preferred choice for software development, game development, and systems programming, offering a rich set of libraries and tools for developers. If you want to become a certified C++ developer, join our C++ Training Program

Features and Benefits of Online C++ Program Compiler

• Accessibility: This Online C++ compiler is accessible from any device with an internet connection, allowing users to write, compile, and run C++ code. You don’t need to install compilers or development environments locally.
• Translation of C++ Code: It does the translation of the source code written in C++ into machine language that the system can understand.
• Optimization: Code optimization technique involves restructuring, loop unrolling, and inlining of functions to reduce execution time and memory usage.
• Advanced Debugging Features: The compiler provides you with debugging support like generating debug symbols, stack traces, and runtime error detection to quickly identify and resolve issues.
• Direct Interaction with Hardware: Leverage the ability to interact directly with hardware, making our compiler ideal for embedded systems development and low-level programming tasks.
• Library Support: The Compiler for C++ language provides standard libraries that provide commonly used functions and data structures. Also, developers can link external libraries to their C++ programs to access additional functionality and resources.
• Cross-Platform Compatibility: The C++ compiler is cross-platform, meaning it can generate executable code for various hardware architectures and operating systems. It provides the leisure to write C++ code once and compile it for different platforms without modification.

How to Use Online Editor for C++?

1. Choose C++ Online Editor: Navigate to the "Platform" tab on the ScholarHat website. Select the "Coding Playground" option in it. The "Learn and Practice with our Coding Playground" page opens.
2. Open the Online Editor: Navigate to the C++ Compiler section and open the C++ editor.
3. Write Your C++ Code: The text editor opens. It's divided into two sections, one for writing code and the other for input/output. Use the text editor to write your C++ program, including any necessary header files, function definitions, and main program logic.
4. Compile Your Code: After writing your C++ code, click on the "Run" button on the right side of the compiler.
5. Check for Errors: If there are any syntax errors or compilation errors in your code, the online editor will display error messages to help you identify and fix them. You can then check for the errors and correct them.
6. Run Your Program: Click the "Run" button to execute your compiled program and see the output on the right side in the output section.
7. Download Your Code: You can also download your code and save it on your computer for future use.
8. Learn and Experiment: Use the online editor to learn new C++ programming concepts, experiment with different algorithms and data structures, and practice coding exercises and challenges.

Common C++ Tags

In the context of C++ programming, "tags" refer to elements or identifiers used in the code, such as keywords, data types, preprocessor directives, and function names.

• Keywords: Keywords are reserved terms in the C++ programming language that have preset meanings. These words cannot be used as identifiers yet are critical to program structure and functionality. Examples: int, char, void, if, else, for, while, return, struct, enum, typedef, switch, case, break, continue, sizeof, static, extern, const, volatile, etc.
• Data Types: A Data Type is a classification of specific types of data by a certain value or certain types of mathematical or logical operations. Examples: int, char, float, double, void, long, short, signed, unsigned, struct, enum, typedef, etc.
• Preprocessor Directives: Preprocessor directives are commands to the C++ preprocessor, which manipulates the code before actual compilation. Examples: #include, #define, #ifdef, #ifndef, #endif, #if, #else, #elif, #pragma, etc.
• Function Names: Function names are identifiers used to define and call functions in C++ programs. Examples: main, printf, scanf, strcpy, strlen, strcmp, malloc, free, exit, rand, srand, tolower, toupper, etc.
• Constants: Constants are fixed values that do not change during program execution. Examples: NULL, EXIT_SUCCESS, EXIT_FAILURE, EOF, INT_MAX, INT_MIN, FLT_MAX, FLT_MIN, DBL_MAX, DBL_MIN, etc.
• Operators: Operators are special symbols used to perform various mathematical and logical operations on variables and symbols known as operands. Examples: +, -, *, /, %, =, ==, !=, <, >, <=, >=, &&, ||, !, &, |, ^, ~, <<, >>, ++, --, +=, -=, *=, /=, %=, &=, |=, ^=, <<=, >>=, etc.

Tips and Best Practices to Run C++ Code Online

• Understand the Environment: Familiarize yourself with the features and limitations of the online C++ compiler. Understand how to create, edit, compile, run, and debug your C++ code within the platform.
• Start with Simple Examples: Test the working of the compiler by writing basic codes. Write basic C++ programs that demonstrate fundamental concepts such as variable declaration, arithmetic operations, conditionals, loops, and functions.
• Check for Language Version and Compiler Flags: Ensure that the online C++ compiler supports the C++ language version and compiler flags you intend to use.
• Handle Input and Output: Understand how to handle input and output in your C++ programs. In this C++ compiler, you can provide input interactively or through standard input streams, and display output in the console window.
• Enable Auto-Save: Enable auto-save or manually save your C++ code regularly to prevent data loss in case of browser crashes or accidental closure of the compiler window.
• Debugging Tools: Use built-in debugging tools and compiler error messages to troubleshoot and fix issues in your C++ code.
• Read Documentation and Tutorials: Read our documentation and tutorials to learn advanced features, tips, and tricks for optimizing your C++ code and leveraging additional tools and libraries.
