Needing Assistance;Unreachable code in function main()

**Mehtabyte** · 11-15-2008

I am new to C++ and have just installed my Borland Compiler.

Here is a very simple program I have written:

Code:

#include <iostream>
using std::cout;
using std::cin;
int main(){
cout<< "My lucky number is ";
int lnum;
lnum = 3;
lnum++;
return lnum;
return 0;
}

However, whenever I try to compile it, I get the following message:

Code:

myfirstprogram.cpp:
Warning W8066 myfirstprogram.cpp 10: Unreachable code in function main()

When I run the program, the "cout" is fine, and the output is "My lucky number is " as specified, but my variable "lnum" is not returned.

Thanks for reading, and please help me with my problem.

It does not make sense to return 0 after returning lnum since control can never reach the line that returns 0. It is only a warning because iit might not really matter, though it may be an indication of a bug. In fact, you might have a bug since it does not make sense to return lnum from main; you probably want to print lnum instead.

Thank you very much for your help. So, would I simply omit:

Code:

return 0;

Well, while you could do that, what you really want to do is to print lnum instead of returning it.

You would also do well to indent your code.

Laserlight: Thanks a lot, I've got it working now =).

Elysia: Thanks, I'll keep that in mind.

Thanks a lot, I can get going on other stuff now! Man, that mistake looks so silly now...
