| 68 | <p>You can use a loop statement when you need to execute a series of
|
|---|
| 69 | statements repeatedly, making an <em>iteration</em>. C provides several
|
|---|
| 70 | different kinds of loop statements, described in the following
|
|---|
| 71 | subsections.
|
|---|
| 72 | </p>
|
|---|
| 73 | <p>Every kind of loop statement is a complex statement because contains a
|
|---|
| 74 | component, here called <var>body</var>, which is a nested statement.
|
|---|
| 75 | Most often the body is a block.
