Explain for loop in PL/SQL with example.

{{**Note: Any other relevant example shall be considered. **}}

For Loop : 

 The FOR LOOP statement specifies a range of integers, then execute a sequence of statements once for each integer in the range. 

 To reverse the range , “REVERSE” keyword is  used.

The syntax is : 

FOR  i IN lower_bound..upper_bound LOOP <loop_body><loop body/statements> 

END LOOP;

OR 

For counter IN [reverse] lower_bound..upper_bound LOOP<loop body/statements>;

END LOOP; 

 Example:

  begin 

For a in 10..20 loop     --output 10 to 20 elements dbms_output.put_line(‘value of a :’ || a); 

End Loop;

  End;
