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

Program A is closed, it had an int with the value 1234 at 0x1234 -> I run my program, myInt gets the address 0x1234...

Note also that because of virtual memory in modern operating system what Program A called address 0x1234 is unlikely to actually refer to the same space in physical memory as what your program calls address 0x1234.
