The for Statement

The for statement has the form:

label_opt for (		expression-1_opt; 
		expression-2_opt; 
		expression-3_opt) statement

It is equivalent to:

expression-1;
while (expression-2) {
	statement
	expression-3;
}

in the absence of continue or break statements. Thus, the first expression is an initialization, the second a test for starting and continuing the loop, and the third a re-initialization for subsequent travels around the loop.
