[FIXED] what does this line of syntax mean in c++?

Issue

this is a quick question, Im translating a program that's in C++ to C, and I saw this line of code,

for (int v : adj[u]) { 

referenced in this article: link

and I am not really sure what it does. I tried googling it and got results for range based for loops in C++, but cannot find anything that has this exact syntax and what it means. Help would be much appreciated.

Solution

It's a very simple for loop that iterates over the elements of adj[u], going 1 by 1.
