How can loops be used to process arrays?

Answer 1

Loops can be used to iterate or walk through an array. For example, suppose you have an array already initialized (we'll call it "array"):

int target = -1;

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

if (array[i] = target){

//do something

}

}

Here, we will walk through an array (note that arrays are zero indexed) using a loop to make sure we hit each element of the array. In our loop, we start at the head (or first element) and iterate over each element.

Answer 2

Absolutely. In fact, using loops to process arrays is one the most fundamental paradigms in programming.
