An Example
	ä Process P1 and P2 are running this same procedure and have access to the same variable “a” ä Processes can be interrupted anywhere ä If P1 is first interrupted after user input and P2 executes entirely ä Then the character echoed by P1 will be the one read by P2 !!
						static char a; void echo() {    cin >> a;    cout << a; }
