Question

Kindly help me fix my display method in this C++ program: http://txt.do/d32k OR http://textuploader.com/d32k

Thank you!

Answer 1

void display(queuetype &queue); \(\leftarrow\) Declaration
void display(queuetype &queue, string newElement) \(\leftarrow\) Function

There is an argument mismatch to start.

Answer 2

Answer 3

I removed "string newElement" from the display function, which gives a declaration error for "newElement." Among other errors.

Could you kindly be more specific?

Thank you.

Answer 4

Where you used it in the code:
```
while (!emptyqueue(elements)) { // this while loop runs whenever returned false
dequeue(elements, elementOut);
cout << elementOut << endl;
display(queue, newElement);
}
```
That means you did not need to delete it in the function implementation, but rather add it to the function declaration.

My second note is a reference to the use of a struct in general.

```
struct queuetype
{
string elementsOfArray[MAX];
int front;
int back;
};
```
Means that to directly access elementsOfArray, front, or back you need to use the dot or arrow operator.
