C++: Uninitialized variables garbage

Question

int myInt;
cout << myInt; // Garbage like 429948, etc

If I output and/or work with uninitialized variables in C++, what are their assumed val

Answer 1

Its value is indeterminate. (§8.5/9)

There's no use trying to get meaningful data from it. In practice, it's just whatever happened to be there.

Most compilers will pack "meaningful" debug data in there in a debug build. For example, MSVC will initialize things to 0xCCCCCCCC. This is removed in an optimized build, of course.
