for almsot 6 hours trying to understand why this program not running ..
visual says: the system canot find file spesifect
can you try to run it? did it run? what should i do?
Kiryu (41)
First of all its a bad habit to post the entire code you have and just ask "why is it not running".
The best place to start is to give us a proper error message.

Does that file really exist?
darje (37)
yes calss ArrayList
the header file

cant understand why this program not runing

sorry, neither could i after trying to read 350+ lines of your code
jonnin (11331)
start over. Build a new project in your tool and bring the code into it, see if you can get the message to clear up. It sounds a little like a corrupted project file, but you didn't give us much to go on. (You don't have to change any code for this, its an attempt to see if you have a tool error only -- you can save what you have).

When you do have a viable project move all the template code into a header file.

https://isocpp.org/wiki/faq/templates#templates-defn-vs-decl
darje (37)
i try to do the projet again keep getting error
moved all the template function to the header file still problem
even delete visual studio and install again same problem.
..
its says unable to start project ...
and says the system cannot find the file specified .
(popup error)
Flaze07 (231)
is the file in the same folder ?

post the full error message, just copy-paste it so there won't be typos.
also, ¿when does this happen?

¿what's the rationale behind this `run anyway' option?

¿what's the rationale behind this `run anyway' option?


I'm not sure what the rationale is, but the default is to ask the user if they want to run anyway.

This references an older version of VS, but it still works the same:
