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.

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

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

              cout<<"the element is:"<<ele[i]<<endl;

             for( int j = 0; j<3; j++)

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

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
