Help for run the C++ code

[Shohag Rezaul Karim]

Hi..everybody! I am new in this forum. Can any one please help me to run the following C++ code? I will be greatfull if any one help me.

Thanks

When I compiled the code, I got 28 errors.
You need to work through the list of errors and correct each one.

For example, you need to pay attention to capitialization.
Line 117:
p[i].Path[tmp]=cr;
Member path is delcared as 'path' (no capitialization) in struct Packet.


BTW, please use code tags when pasting code.

[Shohag Rezaul Karim]

Thanks a lot. I will back soon. pls help me.

[Shohag Rezaul Karim]

Could you please check now? I have got 8 errors. pls help i couldn't resolve it.
Thanks and waiting for your reply.

You still have quite a few errors, including still referring to path as Path. Only one of them is of any difficult to spot:

#define backward -l

I think you want a -1 there, not a -l. Prefer not to use defines.

const int backward = -1; would work fine.

When you're fixing your errors, fix the first error reported, then try to compile again before fixing any more errors. Often times errors immediately after the first reported are a direct result of failing to parse the code where the first reported error occurred.

Getting your code to compile is a major part of programming, keep working on it.

Do not post code on here and say: "I get errors. Please help." Do, if you're having trouble resolving a specific compilation error, post the first few lines of the compiler output beginning with the reported error. Do use code tags when you post. See the <> button to the right of the edit box when you're composing a reply.

I still see 26 errors using VC++.
This includes the error I pointed out in my earlier post which you did not fix.

Cire pointed out another cause of several errors.

printf is undefined because #include <stdio.h> is commented out.

You have a number of careless typos.
Missing close paren, misplaced semicolon, etc.

Please learn to use code tags.
