for directive
Syntax
| for-directive: | for { <expr1> ; <expr2> ; <expr3> } <expr4> |
Description
Use for directive to get loop behaviour. for takes 4 expressions, each of which has its own purpose and term. First expression (expr1) is called "initialization expression," second expression (expr2) is called "condition," third expression (expr3) is "action," and the last expresion outside braces (expr4) is "loop body."
The logic for directive follows is:
1. The initialization expression is evaluated.
2. The condition is evaluated. If it evaluates to 0, the loop ends.
3. The loop body is evaluated.
4. The action is evaluated.
5. Process repeats from paragraph 2.
