1.2.4.1 The while and do while statements
The while loop is simpler than the for loop:
| | while (condition) body_statement
|
The body_statement -- very oten a compound statement enclosed
in curly braces -- executes over and over until the condition
becomes false. If the condition is false to begin with,
body_statement never executes.
Occasionally, you want the body_statement to execute and set the
condition before it is tested for the first time. In
this case, use the do while statement:
| | do {
body_statement_A;
body_statement_B;
...etc...
} while (condition);
