vB Problem Solving!! Urgent, VB exam for help!!

There are two ways to do this, first: with a triple cycle; Second, just write a function call. I'll do it for you here with the second one, first making a method that returns the value of each item:

public function add(byval n as integer) as double

dim i as integer

dim s as double = 1

for i = 1 to n

s = s * 2 * i - 1)

nextreturn s

end function

Second, you can call the above method in a loop, I wrote it in the form load event, and you didn't input that n, it was directly assigned a value, that is, the maximum value of the following i is 100, I'm really embarrassed, because it is troublesome to add controls to the value again.

dim i as integer

dim s as double

for i = 1 to 100

s = s + add(i)

You can try, I just hope you can solve the problem, nothing else matters, because I'm also a newbie......Hehe.

The topic is not clear enough....Not sure what you're asking for....

Single selection 2 a, 0 3 b、good 4 .a、pi*2*r6. c、p and q mod 2=0 and y mod 2=0 and z mod 2=0

8. b、word 9.No program 10 、s=1!+2!+3! +10!Multiple choices. c

ba，b，c

ca, b, d judgment.

(1) In addition to the form, a total of 3 types of controls are used: text box, button, list box (2), here is to assign the text box Chinese text to the variable s

3) B and C should be chosen, where t is the middle value of the "score" and n is the score of the individual letters. The A position has not been calculated for the score n of a single letter, so it is incorrect. The B position and the C position have been calculated for the score n of a single letter, and the n variable between the B position and the C position has not changed, so both the B position and the C position are OK.

The d position is outside the loop and cannot be added up by the loop, so it is incorrect.

4）stress s->19 t->20 r->18 e->5 s->19 t->19 19+20+18+5+19+19=100
