expection handing: error message "undefined symbol try . . "

how to work with expection handing in which when i am using try block then the error message coming that "undefined symbol try" why it is so, please solve my problem.

Can you post the piece of code where u are getting the error?
Also which compiler u are using?

Are you compiling as c or c++?
Is that the only error message you are getting?

then what I should do and how can i run my programme

You should start by re-writing void main() as int main(). Main returns an int, always, anything else is undefined behaviour.

I don't think you started learning C++ by learning exceptions. How did you compile your hello world c++ program?

my problem is "undefined symbol try" how can I handle this

Your problem is not being sure which language you are coding in. You want to use try/catch exception handling so you must use c++ not c.
For c++ you need to change these things

1.) replace #include<iostream.h> with #include<iostream>
2.) Remove all other includes
3.) add using namespace std; before the definition of main
4.) Make main return an int not void. void is wrong even in c
5.) Remove lines with clrscr(); and getch(); in your code
6.) Compile the file as a c++ file not as a c source file.

Something obvious that has not been mentioned yet is what is the name of your file?

if it is <something>.c then the compiler will almost certainly be compiling it as C code it needs to be <something>.cpp

Also, keep in mind that exception handling is often turned off in most C++ compilers by default. You have have to enable it by setting a compiler switch.

That would explain your indefined symbol.
