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

It's not even guaranteed to be a value at all. Trying to read the int, anything can happen (such as a signal sent causing your program to terminate). With particular importance in real life programming, switching on a not initialized bool can cause you hit neither true nor false cases.
