Question

This is one function in .h file

LinkedListElement<char> * findLastNthElementRecursive(int n, int &current);

Try both

findLastNthElementRecursive(3,0);

and

int a = 0;
findLastNthElementRecursive(3,&a);

error is no matching function

I GOT IT findLastNthElementRecursive(3,a); SHOULE BE THIS WAY

but if I do not want to create new variable like a, how to do that?

Answer 1

A temporary cannot bind to a non-const reference. In your first case, you attempt to pass a temorary as parameter, and it fails.

The second one doesn’t work because &a is the address of a, effectively an int*, so doesn’t match the signature of the function.

The correct way would be

int a = 0;
findLastNthElementRecursive(3,a);
