unreachable code warning is at line 435
declaration syntax error is at line 497 or 498.

[weaknessforcats]

When you call a function you don't use the return type. Just remove the void inside main();

[samrah]

I'm sorry I didn't get what you told me to do.Can you explain it please?

[weaknessforcats]

You call a function by:

pg3();
 
 

and not by:

void pg3();

void pg3(); is a function prototype. You can't use it for both a prototype and a call. The compiler won't allow it.

[samrah]

void pg3();
is where i am defining the function and
pg3();
is where i'm calling it.
moreover the error is on line 498.
so please help.i've to submit my project in 3 days.

[weaknessforcats]

I am not able to compile your code from your first post because of problems with mis-matched or missing braces.

You need to compile the code and fix the first error. Then re-compile. Many errors go away when you do this.

Do you have more recent code?
