The break statement in Pascal has the following two usages:

When the break statement is encountered inside a loop, the loop is immediately terminated and program control resumes at the next statement following the loop.

  1. It can be used to terminate a case in the case statement (covered in the next chapter).
  2. If you are using nested loops ( ie. one loop inside another loop), the break statement will stop the execution of the innermost loop and start executing the next line of code after the block.

 

1. Syntax:

The syntax for a break statement in Pascal is as follows:

break;

 

2. Flow Diagram:

cpp break statement

 

3. Example:

program exBreak;
var
   a: integer;
begin
   a :=10;
   while (a<20) do
    begin
      writeln('value of a: ', a);
      a:=a +1;
      if (a>15) then
       break; {terminate the loop}
    end;   
end.
 

When the above code is compiled and executed, it produces following result:

value of a: 10
value of a: 11
value of a: 12
value of a: 13
value of a: 14
value of a: 15
