removeElement() Breakdown

In this chapter, we will do a full breakdown on how to complete the removeElement function

//Exam Question 1: Complete the implementation for removing elements
int removeElement(struct listElement **targetList, int targetIndex){
	//Recall from lecture - why do we need a double pointer for targetList?
	//1. Remove Head Elements
	//2. Remove Tail Elements
	//3. Remove Middle Elements
	//use addElement() implementations for reference

	// YOUR IMPLEMENTATION HERE

	return 0;
}

🧠 Why do we need a double pointer for targetList?

We use a double pointer (struct listElement **targetList) because we might need to change where the head of the list points — especially when removing the first element.

If we used a single pointer, we’d only be modifying a copy of the head pointer. The original list in main() would stay the same. But with a double pointer, we can update the actual head pointer, and that change will be seen outside the function.
