Do not use a semicolon on the same line as an if, for, or while statement because this typically indicates programmer error and can result in unexpected behavior.
In this noncompliant code example, a semicolon is used on the same line as an if statement.
if (a == b); {
/* ... */
}
|
It is likely, in this example, that the semicolon was accidentally inserted.
if (a == b) {
/* ... */
}
|
Placing a semicolon on the same line as an if, for, or while statement may result in unexpected behavior.
