+Create a program that models a shopping cart for a e-commerce website. The program should include the following structs:
+
+- `Item` struct, with fields for the item's name, price, and quantity.
+- `Cart` struct, with a field for a slice of Item structs and methods for adding an item to the cart, removing an item from the cart, and calculating the total cost of the items in the cart.
+
+Your program should allow a user to create a new cart, add items to the cart, remove items from the cart, and display the total cost of the items in the cart.
+
+Here is a skeleton of the code
+
+```Go
+package main
+
+type Item struct {
+    name  string
+    price float64
+    quantity int
+}
+
+type Cart struct {
+    items []Item
+}
+
+func (c *Cart) AddItem(i Item) {
+    // Add code here to add an item to the cart
+}
+
+func (c *Cart) RemoveItem(name string) {
+    // Add code here to remove an item from the cart
+}
+
+func (c *Cart) TotalCost() float64 {
+    // Add code here to calculate the total cost of the items in the cart
+}
+
+func main() {
+    // Create a new cart
+    cart := Cart{}
+    // Add items to the cart
+    cart.AddItem(Item{name: "item1", price: 10.0, quantity: 1})
+    cart.AddItem(Item{name: "item2", price: 20.0, quantity: 2})
+    // Remove an item from the cart
+    cart.RemoveItem("item1")
+    // Display the total cost of the items in the cart
+    fmt.Println("Total cost: ", cart.TotalCost())
+}
+```
+This is just a skeleton code, you need to write the logic for the AddItem, RemoveItem and TotalCost function.
+
+This Assignment will check your understanding of creating struct, composing them and using pointer receivers.
