Simple for () {}

  for (i=0; i<N; i++) {
    statement_1;
    statement_2;
      .....
  }

The general form

  for (initialization_statement; continuation_condition; iteration_command) {
    statement_1;
    statement_2;
       ...
  }

is analagous to that in Perl - in this,

• initialization_statement is the statement to execute when the loop is first entered;
• continuation_condition is the condition that must be satisfied in order that the next iteration take place;
• iteration_command is the command to be executed each time through the loop;

If there is only one statement to be iterated over, the matching curly braces may be omitted:

  for (i=0; i<N; i++)
    statement;
