Comparison between Looping Statements

For …Next Statement

Do …. While Statement

It is one of the limited loop statements
used when we want to repeat a code for
specific number of time . It needs
numeric variable (integer or decimal) to
work as a counter with start value , end
value and add or increment value .

The statement 'Do while ... loop' is used
to repeat a specific code for a several
times of an unknown end, but based on a
specific condition, so they are useful if
you do not know the number of iterations
emphatically.

The repetitive code will be implemented
(executed) as long as the counter variable
is less than or equal the end value .The
loop stops when the value of the counter
exceeds the last value.

The repetitive code will be implemented
(executed) as long as the conditional
expression is true. If the condition is not
met for any reason, we get out of the
iterative loop, and implement the code
after the Loop if it exists.
