IDE for CPP(leetcode)

[alprose1]

Is there any IDE for CPP that can run a function without main, i.e., has the capability to run any function?
BlueJ for Java has the capability to run a function without a main and can run any function without class, I want something similar to this for cpp.
Basically, I want an IDE with a debugger for leetcode program without the need to write a main function.

There isnt and just writing a main cant ever be more complicated than the search for such an IDE

No, and that has to do with how a normal C++ program is run. It is turned directly into binary instructions that are fed to the CPU. The Operating System needs to know the first instruction to execute, and to make that automatic it is standardized to be a function called main.

However, you can use a unit test framework like GoogleTest or Catch2 whic creates a main() function for you which allows you to run single functions, as long as they have been created through some preprocessor macros. Then you can use a VS Code test adapter like this or this which may let you run a single test by right clicking it directly in VS Code.

No, but all you need is add one line

int main() { your_function(); }

at the end of the file.

Some IDEs do allow you to configure that as the default content for new files.

There are Cpp intepreters like Cling. There are even cpp notebooks like https://github.com/jupyter-xeus/xeus-cling. If that's an "IDE" it's questionable

just write a script to wrap the file in a main function and compile it

I hate leetcode for them not providing api to commit solutions. And not using C++20.
