C++ is a superset of C, so 90% of that code is already in C - the cout stuff needs to be replaced by printf statements is all.

But ... first you will have to find an SHA-256 C library that you can use, as it's not a part of standard C at all. Google is the place to start: sha256 c library - Google Search[^]

There is no converter. You have to rewrite the code from scratch, by understanding what the original code does and writing equivalent code in C.

No, nobody is going to that for you.
