I’m trying to redirect a signed char to cout. It works fine under Windows/VS2019 thanks to How to output a character as an integer through cout?.
However, under Android, compiled with CLang, it does not behave as expected.
Here is the code:
char c = -1; std::cout << "c signed is " << signed(c) << std::endl; std::cout << "+c is " << +c << std::endl;
Under Windows, I get expected output:
c signed is -1 +c is -1
Under Android, I get expected output:
c signed is 255 +c is 255
What portable code would help displaying "-1" on all platform?
