We'll happily help you, Skills, but only after you've shown to us that you've made an attempt yourself. Think of us as a last resort, not a go-to for problem solutions. :)

cant any1 help me in doing this??plz be a human begin n help me.plz plz only case 3....plz plz plz.
coder777 (8439)
I strongly suggest to use code tags see my post above

Did you ever compile it? After 'case 2' you have a function within the (main) function which is not allowed. Place those functions before main and call them accordingly.

For your 'case 4' (which is actually 'case 3') call printForm() is what you want? Like I said relocate and then call them.

yes i have compiled it and it working uptil case 2. and plz can u help me in doing this please.
closed account (zb0S216C)
I do believe that you're defining a method within your case 2. This is not allowed. Place getData( ) outside of main( ). Then, within case 2, call getData( ).

P.S: Please use code tags. Without code tags, your code becomes harder to read.

Ok, I made it compile (not more! and since you don't like code tags...):

switch(ticketType)

What do you mean "since you don't like code tags"?

pardonnez-moi? Since the OP didn't use code tags and I didn't want to bother reformating all I omitted the code tags just like he did

Sorry, I misread your username (or didn't read it) and assumed it was the OP >_<

Mixing different types with cin,
is not very safe. There is a thread about it here

http://www.cplusplus.com/forum/articles/6046/

Is a temporarily fix,.. in modified version of your code below I have replaced
I think you have to do it another way, or at least specify that the input to cin should be threated as a hex
when reading the seat information ( not obvious as the letter A - E can be either a hex number or text )

i.e replace

cin >> option;

with

cin >> hex >> option;


You should probably also change it a couple of other places (or even better have a look at the article link above)
The code below compile and works for me, but crashes if the name is a double name.

there is a error in case 2

Posting the error you're receiving would help.
