convert c program to c ++ online

Certainly! To convert a C program to C++ online, follow these steps:

  1. Change File Extension:

  2. Rename the file from .c to .cpp to indicate that it's a C++ file.

  3. Include Headers:

  4. Replace <stdio.h> with <iostream> for input/output operations.

  5. Namespace Usage:

  6. Use the std namespace to access standard C++ functionality.

  7. Add using namespace std; or prefix cout, cin, etc., with std::.

  8. Replace Standard I/O Functions:

  9. Replace printf() with cout for output.

  10. Replace scanf() with cin for input.

  11. Dynamic Memory Allocation:

  12. Replace malloc() with new for memory allocation.

  13. Replace free() with delete to deallocate memory.

  14. Type Casting:

  15. Use static_cast<>() or dynamic_cast<>() for type casting instead of (type).

  16. String Handling:

  17. Replace C-style strings (character arrays) with std::string for string handling.

  18. Function Prototypes:

  19. Replace function prototypes outside of main() with function declarations in a class or above main() if using C++ style.

  20. Error Handling:

  21. Utilize C++ exceptions (try, catch) instead of C-style error handling.

  22. Classes and Objects (if necessary):

    • Transform parts of the code into classes and objects if object-oriented features are desired.

  23. STL Usage:

    • Utilize C++ Standard Template Library (STL) for containers (e.g., vector, list, map) and algorithms (e.g., sort, find).

  24. Other C++ Features:

    • Implement C++ specific features like function overloading, operator overloading, and templates if necessary.

Ensure to review and adapt each step based on the specific requirements of the program and the C++ features you intend to use.
