Answer:
1. nested loop join is a naive algorithm that joins two sets by using two nested loops. Join operations are important for database management.
2.If condition is True, all statements are executed until the Wend statement is encountered. Control then returns to the While statement and condition is again checked. If condition is still True, the process is repeated. If it is not True, execution resumes with the statement following the Wend statement

Answer:
1) The For statement specifies the counter variable and its start and end values. The Next statement increments the counter variable by 1. Using the Step keyword, you can increase or decrease the counter variable by the value you specify.
2) A nested loop join is a naive algorithm that joins two sets by using two nested loops.
3) VBScript While...Wend Loop. In a While..Wend loop, if the condition is True, all statements are executed until Wend keyword is encountered. If the condition is false, the loop is exited and the control jumps to very next statement after Wend keyword.
