The
syntax for the do...while statement is as follows:
|
do
statement
while
(condition);
|
statement
is executed, and then condition is evaluated. If
condition is TRUE, the loop is repeated; otherwise,
the loop ends. The statements and conditions are
otherwise identical to the while loop. Example 1
//
count to 10
int
x = 0;
do
cout
<< "X: " << x++;
while
(x < 10)
Example
2
//
print lowercase alphabet.
char
ch = ‘a’;
do
{
cout
<< ch << ‘ ‘;
ch++;
}
while ( ch <= ‘z’ );
DO
use do...while when you want to ensure the loop
is executed at least once. DO use while loops
when you want to skip the loop if the condition
is false. DO test all loops to make sure
they do what you expect.
