| 4 | SYNTAX |
| 5 | for(init; expr2; expr3) statement; |
| 6 | |
| 7 | DESCRIPTION |
| 8 | Execute <init> once. Then, while <expr2> returns a non-zero |
| 9 | value, execute <statement>. Every time <statement> has been |
| 10 | executed, or a 'continue' statement has been executed, execute |
| 11 | <expr3> before next loop. |
| 12 | |
| 13 | <init> is usually a series of one or more expressions (remember |
| 14 | that assignments are expressions, too), separated by commas. |
| 15 | Additionally it is also allowed to define new local variables |
| 16 | here and assign them an initial value. The scope of such variables |
| 17 | is the whole for statement. |
| 18 | |
| 19 | Examples for legal <init> expressions are: |
| 20 | |
| 21 | for (i = 0; ... |
| 22 | for (i = 0, j = 0; ... |
| 23 | for (i = 0, int j = i; ... |
| 24 | for (int j = 4; ... |
| 25 | |
| 26 | Illegal <init> expressions are: |
| 27 | |
| 28 | for (int i; ... : no value assigned |
| 29 | for (int i += 4; ... : only plain assignments allowed |
| 30 | |
| 31 | A 'break' in the 'statement' will terminate the loop. A |
| 32 | 'continue' will continue the execution from the beginning of |
| 33 | the loop. |
