for Loop

The "for" keyword is used to set up a loop to repeatedly execute the statements in its range until a certain condition is met. In the parentheses after the keyword "for", you define a starting value, an ending condition, and how to increment (or decrement) to reach the ending value. These are separated using ;

	for (starting value; ending condition; increment)) {
	    execute this step 1;
	    execute this step 2;
	    execute this step 3;
	}

An example might look like the following. The integer i will go from a value of 0 to 9. The integer k will go from a value of 0 to 45 in multiples of 5. The integer m will go from 0 to 63 in multiples of 7.

	int k;
	int m;
	for (int i=0; i < 10; i++) {
	    k = 5 * i;
	    m = 7 * i;
	}
