please check your opening braces '{' and closing braces '}.
And Why use switch case for only one condition ?

1. i checked up every braces { and }
2. i use switch for 1 = loop; 2 = exit.

* edited original cpp code, still gaving me the SAME errors *

the error is in line 20...
int main();... remove the ;
closed account (z05DSL3A)
Applying some basic formating to the code will show that there is more than just the semicolon wrong.

@ Mathes : same problem.
@ Gray Wolf : same problem.

vladdo. Grey Wolf was simply pointing our that there are a variety of problems with your code.

Make sure that you remove the ; after function declarations.

I.e.
1
2
 
main()
{

not
1
2
 
main();
{


Also, make sure that all of your code is in correct blocks. Looking at case '2' should be a good place to start here.

There are many mistakes in this code, and us pointing them all out isn't going to help you. Look at it carefully.
