i create a template class with a constructor but don't know why i get this error

datalib.cpp: In function ‘int main()’:
datalib.cpp:260:20: error: invalid conversion from ‘Queue<int>*’ to ‘int’ [-fpermissive]
  260 | Queue<int> queue = new Queue<int>(200);
      |                    ^~~~~~~~~~~~~~~~~~~
      |                    |
      |                    Queue<int>*
datalib.cpp:208:11: note:   initializing argument 1 of ‘Queue<T>::Queue(int) [with T = int]’
  208 | Queue(int capacity){
      |       ~~~~^~~~~~~~

new returns a pointer

#

but why are you using dynamic memory aka new?

I think he is trying to allocate Queue size

hidden bone
#

should be irrelevant, the Queue should handle that internally

#

here the Queue object itself is being made dynamically, when there's likely no reason for it to be

supple jetty
#

yeah but that's most likely what he was trying to do 😅

Queue<int> queue(200);

give me a sec

#

Or just send it here actually. Just make sure there is no template right before int main(){...

foggy harness
#

there is a templeate since my teacher doesn't allow us to use libraries

supple jetty
# 
template<...> // you need to delete this line
int main() {
    // ...
}
foggy harness
#

why?

#

before main is just a };

#

from a class

supple jetty
#

Hmm

#

You should send the code so we can see what is going on though.

supple jetty
#

Did you forget a semicolon somewhere? lol
