Answer: Iteration

Each pass through a loop is called iteration.

Iteration is the repetition of a process in order to generate a (possibly unbounded) sequence of outcomes. The sequence will approach some endpoint or end value. Each repetition of the process is a single iteration, and the outcome of each iteration is then the starting point of the next iteration.

In mathematics and computer science, iteration (along with the related technique of recursion) is a standard element of algorithms.

Iteration in computing is the technique marking out of a block of statements within a computer program for a defined number of repetitions. That block of statements is said to be iterated; a computer scientist might also refer to that block of statements as an "iteration".

The pseudocode below is an example of iteration; the line of code between the brackets of the for loop will "iterate" three times:

a = 0
for i from 1 to 3        // loop three times
{
  a = a + i              // add the current value of i to a
}
print a                  // the number 6 is printed (0 + 1; 1 + 2; 3 + 3)

It is permissible, and often necessary, to use values from other parts of the program outside the bracketed block of statements, to perform the desired function. In the example above, the line of code is using the value of i as it increments.
