I have a task
I need to Implement a program for extracting function calls and their arguments from the texts of C ++ programs. The program accepts text as input, should output text at the output, where information on the functions found is displayed in separate lines. Each line of output is a sequence of elements, separated by spaces: the name of the function, and the arguments.

What I have tried:

what i need to do?
i know that i need scan the text to find the methods pattern in the text but the question is is regular expression enough for this task or there is a tool to do that and i do not need to invent the wheel?
is it possible to implement this task in c# or better in java

You can use either language, but Google for language parsers, as there are a number of libraries that could assist you.

i have been searching for a week there are many answers. Some people say that is enough to use regex and other said it is better not to reinvent the wheel and use suitable parser and I am new in this field. I need some help

It is possible to implement it in either C# or Java, but a Regex will not be sufficient: there are far, far too many varieties of method signature (and other code) that you need to deal with to make a regular expression viable.

Instead, look at finding a C++ parser in your prefered language and see what you can do with that - it's a major job to produce your own!
Google will help: C++ parser - Google Search[^] is a starting point.
