Answer / namrata
In while first condition is checked if condition is not true
then while don't work and not give output but in do while
loop condition is checked when loop is worked at one time
and if the condition is not true then at least one time it
gives output it is the main difference between while & do
while loop.

Answer / ashok
(1)while loop is known as entry control loop.
and do while is known as exit control loop.
(2)in while loop first check given the condition & if it is
true then execute all statement of while loop.if it is
false then terminate control from loop.
and in do while loop first execute all statement of it and
then check condition, if yes it is true, then again do
while loop will execute, if it is false then terminate
control from loop,put semicolon after while statement.

Answer / shwetha karkera
In WHILE STATEMENT, the condition is tested first, and then
the statements are executed if the condition turns out to
be true. hence, it is calles as PRE-TESTED LOOPING
CONSTRUCT.
In DO WHILE STATEMENT,the statements are executed for the
first time and then the conditions are tested. if the
condition turns out to be true,then the statements are
executed again.hence it is called as POST-TESTED LOOPING
CONSTRUCT.
SYNTAX FOR WHILE STATEMENT:
while(condition)
{
statement;
}
SYNTAX FOR DO WHILE STATEMENT:
Do
{
statement;
}
while(condition)
