decTicketPrice                    ?ticket price

intAge                                  ?age of customer   

 

If customer's age is less than 6, ticket price is Free

 

If customer's age is 6 to 12, ticket price is $3.50

 

If customer's age is 13 to 19, ticket price is $4.50

 

If customer's age is over 62, ticket price is $5.50

I do know how to do them I just need to do them quickly and I take awhile when I write my code

Just copy and paste, then modify, the examples at my link above.

He wanted it quick, but the time between posts was longer than it would have taken, like 2 minutes.

 

Not even that... In fact, it would have taken longer to type up the OP than write the elseif clause he wanted...

Anyone who can not use If statements, case select, or for if loops should not

be in a programming class.

Programming classes are there to teach, are they not? 

 

Although I think if someone has trouble with something this simple, they might want to take up another skill. Like knitting.

Yep, I learned LONG ago that programming was not for me.

10 price = 7.50
20 if age > 62 then price = 5.50
30 if age < 20 then price = 4.50
40 if age < 12 then price = 3.50
50 if age < 6 then price = 0

 

Wait, was this supposed to be in Commodore 64 BASIC?

 

(Yes, this is a horrible example of coding, it's deliberate)

Some more examples for your education:

/* REXX */
arg intAge .

select
when intAge <   6 then decTicketPrice = 0
when intAge <= 12 then decTicketPrice = 3.5
when intAge <= 19 then decTicketPrice = 4.5
when intAge >  62 then decTicketPrice = 5.5
otherwise              decTicketPrice = 7.5
end

return decTicketPrice

Cobol

01 DECTICKETPRICE			PIC S9(5)V99 COMP-3.
01 INTAGE				PIC 9(3) COMP-3.

EVALUATE TRUE
WHEN INTAGE <  6
	MOVE ZERO TO DECTICKETPRICE
WHEN INTAGE <= 12
	MOVE 3.5  TO DECTICKETPRICE
WHEN INTAGE <= 19
	MOVE 4.5 TO DECTICKETPRICE	
WHEN INTAGE >  62 
	MOVE 5.5 TO DECTICKETPRICE
WHEN OTHER
	MOVE 7.5 TO DECTICKETPRICE
END-EVALUATE.

Thanks for all the help guys! Every one of your helpful comments contributed to me getting an A on the assignment!

 

Now there's a misrepresented grade if ever I saw one.

Tbh it seems the OP didn't even try to do this.

if you pseudocode what is required for this you have pretty much written the code....especially considering its to be written in vb.

if x = x then

y = y

else

if x = z then

y = y1

else

'etcetceyc

if you are doing a programming course OP and your posting like this.......you wont get far im sorry.

decTicketPrice                    ?ticket price

intAge                                  ?age of customer   

 

If customer's age is less than 6, ticket price is Free

 

If customer's age is 6 to 12, ticket price is $3.50

 

If customer's age is 13 to 19, ticket price is $4.50

 

If customer's age is over 62, ticket price is $5.50

 

Otherwise, ticket price is $7.50

All values of age were covered in the criteria; so no need for any 'else' statements.

 

But if you insist:

 

float decTicketPrice = 7.50;   // default ticket price

if (intAge < 6) decTicketPrice = 0.00 // under 6 are free

     else decTicketPrice = 3.50; // 6 and over base price is 3.50

 

/* The above statement just screwed up the teacher's requirement */

/* of an 'otherwise' ticket price since the customer is either under 6 */

/* or 6 or above. Dumb teacher giving dumb assignment fails.         */

 

if (intAge > 12) decTicketPrice += 1.00; // over 12 adds a dollar

if (intAge > 62) decTicketPrice += 1.00; // over 62 adds another dollar

VB doesn't use semicolons to end a line ;)

Doesn't cover the $7.50 cost if they are between 19 and 62.

Okay.

unsigned int intAge

// should be unsigned because negative ages aren't possible

// char is also permissible since people aren't likely to be > 255 years old

 

float decTicketPrice = 7.50   // default ticket price

 

if (intAge < 6) decTicketPrice = 0.00 // under 6 and you're in for free!

if (intAge > 5) and (intAge < 13) decTicketPrice += -4.00 // nice discount.

if (intAge > 12) and (intAge < 20) decTicketPrice += -3.00 // decent discount

if (intAge > 62) decTicketPrice += -2.00 // why the hate for senior citizens?

 

 

Still, no real reason for "else" conditions.

Start with the default and go.

The reason is the assignment called for it.

 

Assignments are rarely designed to be the most efficient, but rather to teach a concept.

 

Not that it matters, the OP is clueless and wanted a handout.  And got it.

True, I suppose.

I always received 'extra credit' for thinking beyond the assignment though.

Heh, where I went, the instructors weren't allowed to give you extra credit.
