Subsection Which to Use: for vs. while
Both
for-loops and
while-loops repeat code, but they serve different purposes. Choose the loop that matches your situation to make your code easier to read and understand.
Table 35. Comparing for-loops and while-loops
Requires
a fixed list of values (often 1:N)
a logical condition
Behavior
repeats once per value in the list
repeats while the condition is true
Terminates
after the last value is used
when the condition becomes false
Best when
you know exactly how many iterations you need
you do not know how many iterations you will need
Technically, any
for-loop can be rewritten as a
while-loop and vice versa. However, using the loop that naturally fits the problem makes your code clearer.
