I'm newer to C .
I've written the following line in a test function inside a standard VS2019 test project:
auto minAndMaxYards = std::minmax_element(simResults.begin(), simResults.end());
It yields both C2039 and C3861 errors for the minmax_element function even though intellisense recognizes it as a member of std, and I can peek its definition. I can't figure out what I'm missing. I've included the algorithm file as well at the top of the test project.
Is there a project setting that I don't have right?
Full error text:
C2039 'minmax_element': is not a member of 'std'
C3861 'minmax_element': identifier not found

CodePudding user response:
Move #include "pch.h"
to the top of the file. When using precompiled headers, the compiler ignores everything above this line. In your example, that would be #include <algorithm>
, that's why std::minmax_element
is not found.
