Iteration is implemented in programming using FOR and WHILE statements. In programming, iteration is often referred to as ‘looping’, because when a program iterates it ‘loops’ to an ...

FOR x ← 1 TO 10 FOR y ← 1 TO 10 result ← y * x OUTPUT y + " * " + x + " = " + result ENDFOR ENDFOR For every iteration of x, y is iterated ten times. Nested iteration isn't limited to FOR loops.
