  5. Looping • Want to be able to do things more than once • Basic: • for(vari=initial; while-clause; increment) { statement; } • Example: loop.html

  6. Looping through an array • Attribute of an array: length • Because first entry is 0, loop while < length

  7. Nesting Loops • When you need to work with two or more numbers • Examples • Creating a table • Computing the area of a range of rectangles • …

  8. While • Want to end the loop based on some condition • Need to be changing something to cause it to end Test first: while (condition) { statements; } Test last: do{ statements; } while(condition);
