Could you please write a code in c or c$++$ for this algorithm? i found an answer in chegg but it didnt work well. it gave me many errors.Algorithm for Connectedness and Components:

The following algorithm checks the connectedness of graphs.

S$-1$: Set $H=G$ and component count $c=1.$

S$-2$: Choose an arbitrary vertex $v$ of $G.$

$S-3$ : Fuse all vertices in the neighbourhood $N(v)$ with $v$ and call this vertex $v.$

$S-4$ : If the number of vertices which are non$-$adjacent to $v$ is the same as that before the

fusion, then go to Step$-5.$ Otherwise, go to Step$-2.$

S$-5$ : Delete the vertex $v($with all fused vertex$)$ from $H$ call this new graph $H.$

S$-6$: If $H$ has any vertex left in it$,$ then let clarrc$+1$ and go to Step$-2.$ Otherwise, go to

Step$-7.$

S$-7$ : Print each $c$ with its vertices. Stop.
