#include<bits/stdc++.h>

using namespace std;
int main(){
}

Noah Frederick wrote an excellent article on how to use ultisnips to create "skeleton" files:

Basically, his script detects when a file is created and triggers a pre defined snippet. Of course you have also to install ultisnips.

Someone could ask: Why do not create a file template and trigger it via autocommands? The answer is simple, the ultisnips solution allows you to change your template on demand, it is no just a static template and you can see Noah explaining the ideas behind his solution.

    call plug#load('ultisnips')

Just save that file as a vim template to $HOME/.vim/templates/cc.tpl. Whenver you edit a new file named foo.cc -- voilà!
