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)
