'colon' and 'auto' in for loop c++? need some help understanding the syntax
(3 answers)
Closed 7 months ago.
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.
It's a very simple for loop that iterates over the elements of adj[u], going 1 by 1.

Checking if a double (or float) is NaN in C++
(21 answers)
Closed 4 years ago.
of course I know I should write better code which just not create NaN values.
But is there any casual method to avoid it. I mean something like:
if (!(floatNumber == NaN))
// do some stupid function
else
return;
But it doesn't work for me. I also tried floatNumber==null, but also no result.
Could you please help me?
To test whether a number is NaN, you can use the standard library function std::isnan.

You can use an XML parser library. Here is a link to one such library: http://xerces.apache.org/xerces-c/
