class inside class

You want to move an arbitrary element of the array to the front, and move the other elements over? You could just swap it down the array, I guess.

What does mean?

queue.cpp:149: error: expected constructor, destructor, or type conversion before âQueueâ

template <class T>
Queue Queue<DataType>::Mutofront( T Muele,int n)// in this part of code 

P.cpp:38: error: no matching function for call to âQueue<int>::Mutofront(Queue<int>&, int&)â
queue.cpp:160: note: candidates are: int Queue<DataType>::Mutofront(T, int) [with DataType = int]

Helloooo

[Bazzy]

You didn't give a template argument for the return Queue type.

thanks Bazzy

I working with these functions to move to the front the nth element, Can some one figure out those errors

queue.cpp: In member function âvoid Queue<DataType>::Mutofront(const Queue<T>&, int)â:
queue.cpp:174: error: expected primary-expression before âelseâ
queue.cpp:174: error: expected `;' before âelseâ

void Queue<DataType>::Mutofront(const Queue<T>& Muele,int n)
{

       for (int i = 0 ; i <3; i++){

         if ( n == ele[i]){
              cout<<"the element is:"<<ele[i]<<endl;

             for( int j = 0; j<3; j++)
               
                  int temp = ele[i];
                  
                  ele[i]= ele[j];
                 
                      ele[j] = temp;


         else
            cout<< "No mach"<<endl;
      }
   }

 Display( );

The for doesn't have braces.
The if's true block never closes.

[Bazzy]

You have if closing brace at the wrong position, you should move it before else
You should also enclose lines 11-15 in braces to be executed inside the for loop
