The application uses C since we're performing simple calculations with basic algebra. It wouldn't make sense to use C++ in this case. That would introduce the added step of ensuring the functions we need to call from JavaScript are wrapped in an extern block. We'll write the calculation functions in a single C file and compile it down to a single Wasm module. We can continue to use VS Code's Tasks functionality to perform the build, but the arguments will need to be updated since we'll only compile a single file. Let's move on to project configuration.
