+**`cend()`** takes no parameters and returns a constant iterator pointing to the element 
+after the last element in the array
+
+## Syntax
+```pseudo
+array.cend();
+```
+
+## Example: Using cend to get Last Element
+
+This example prints the last element using cend()
+
+```cpp
+
+#include <iostream>
+#include <array>
+
+int main() {
+    std::array<int,2> array = {1,2};
+    //gets iterator after last element
+    auto it = array.cend();
+    //uses iterator to get last element 2
+    std::cout << *(std::prev(it)) << "\n";
+    return 0;
+}
+```
+
+The output of the program above will be:
+
+```shell
+2
+```
+
+## Codebyte Example: Using Cend to print array
+
+The following code makes an array and uses cend to print out all of its elements.
+
+```codebyte/cpp
+#include <iostream>
+#include <array>
+
+int main() {
+  std::array<int,4> array = {1, 2, 3, 4};
+
+  //prints all elements in array
+  for(auto i = array.cbegin(); i != array.cend(); ++i){
+    std::cout << *i << " ";
+  }
+
+  return 0;
+}
+```
+The output of the program above will be
+```shell
+1 2 3 4
+```
