What will this C code do?

void main(){
int x=1;
printf("%d\n",x=2);
}

A different C program or a different translation unit? I don't know about a different C program (not sure how that would work out), but objects with static duration are initialized before program startup, so the behaviour would be defined.

Informally, in C, variables are named objects. These variables have scope, duration, and linkage. Also, an object is a runtime thing. Ie, it doesn't exist at compile time. Eer....why am I arguing with some faggot that thinks global variables are static?

Why don't you just fucking read the standard and write some code you moron.
