This was tested in SoloLearn's C++ Playground, I'm making the assumption my compiler will do something similar to the one SL uses.
So, I'm playing around with std::array<T, s>, because I plan on using it in my game.
When I do std::array<bool, 5> def; and print out the items in each index, I get:
Default 0: 0
Default 1: 0
Default 2: 0
Default 3: 0
Default 4: 0
When I do std::array<std::string, 5> def;:
Default 0:
Default 1:
Default 2:
Default 3:
Default 4:
however, when I use an integral type like int, I get numbers that are totally random in some of the spots. - Only a few are actually initialized with 0 (like I expect).
Here's a sample:
Default 0: 1875674416
Default 1: 32568
Default 2: 0
Default 3: 0
Default 4: 4199168
So, is there a way I can get these integral types to initialize properly? Or do I have to manually initialize the array with 0 (somehow)?
