Question

Given a one-dimensional array named yearlySalesTotals that contains decimal values, code the first line of a for statement that declares an index, a Boolean expression for ending the for loop, and an increment expression that lets you use the index to refer to each element in the array.

Answer 1

Answer:

for(int i =0; i<yearlySalesTotals.length;i++)

Explanation:

The for statement in has the syntax as given above, it has an int variable indicating the starting index, then a boolen condition ensuring that you don't get out of the array bounds, and an increment operator.

See below a complete program in java that will output all elements of the array  assuming the array yearlySalesTotals contains only ten elements and all indexes has been assigned values.

public class ANot {

   public static void main(String[] args) {

double []yearlySalesTotals = new double[10];

for(int i = 0; i<yearlySalesTotals.length; i++){

   System.out.println(yearlySalesTotals[i]);

   }

}

}
