Loop structures: Difference between revisions

===For Loop===

A <CODE>for</CODE> loop is really a <CODE>foreach</CODE> loop that can work with range operators or iterate through various data structures. The <CODE>to</CODE> operator creates an enumerating expression that lazily steps through its range.

for i = 1 to 1000000

{

println[i]

}

 

The <CODE>to</CODE> operator can be combined with a <CODE>step</CODE> statement:

for i = 1 to 1000000 step 3

println[i]

 

As a <CODE>foreach</CODE> statement. The <CODE>for</CODE> construct can iterate over the elements of an array, set, dictionary, or enumerating expression.

for i = [2,3,7,9]

println[i]

 

===Do...While Loop===

i=0

do

i = i+1

} while i<1000
