If a hypothesis has been tested many times (using approved experimental methods), and each test has proven the hypothesis to be true, the hypothesis can be taken to be a fact, or truth.
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.

The multiplication fact (singular, not plural 'facts') that can be found is 7x9 = 63. Using the arrays, a 2x9 array (2 rows of 9 items) and 5x9 array (5 rows of 9 items) is 63: 2x9 = 18 5x9 = 45 18 + 45 = 63
You can see that multiplication works both ways: 2x9=18 9x2=18 5x9=45 9x5=45 Arrays are also helpful in seeing the inverse relationship between multiplication and division.
Records are distinguished from arrays by the fact that their number of fields is typically fixed, each field has a name, and that each field may have a different type.
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.
sorry, yes in fact you need to use forge.
Yes. Absolutely. In fact, the power of arrays becomes very obvious when you start to build looping constructs such as while, do, for, etc.
Some people who had been killed using the death penalty have been found not guilty after the fact.
