Use a For-Loop to step through an Array

[louiecerv]

The For-Loop is the perfect mechanism for stepping through the elements of an array.  For example, the following for loop illustrates how you can step through an array:

Code: [Select]


for (int index=0; index<temp.length; index++)
{
    temp[index] = keyboard.nextDouble();
    sum += temp[index];
}

Also this expression is equivalent to while loop

***********************************

int index=0;
while (index <temp.length) {
    temp[index] = keyboard.nextDouble();
    sum += temp[index];
}

Hey Mark, you forgot to increment index inside the while loop.
