Question

In continuation with my first question

Answer 1

Answer 2

Baptiste E. Prunier
If c is run in client side using WASM then I don't think that every user have installed WASM in their PC.

Answer 3

I don't know about c language in web development. I not be used.

But:
Without HTML no webpage is possible.

Answer 4

HTML, CSS, Javascript run on the client inside the browser, PHP runs on the server...
So a C program can run on the server by CGI.

Answer 5

SPace I think it is interpreted by the browser so it is the same problem as HTML5 : it depends if the browser handle it or not
