What are the default value for initialized variable?

e.g.

int d; // debug give me -858993460
char c; // debug give me -52

I am using VS.net 2005

It's either unspecified or implementation defined.

However, in the case of VS, it's all cc's.

The word the standard uses is INDETERMINATE.

For the contents of d and c. The word the standard uses for
"reading" the indeterminate contents of d is "undefined
behavior".

It's a gross piece of insanity left over from historical
C stupidity that certain types neglect to perform their
default initialization at times (the default initialization
of int and char is to zero initialize them by the way).

Well, I can't disagree with that.
