+# pop_back
+
+**Description** : The list::pop_back() function in C++ STL removes the last element in the list container.
+
+**Example**:
+
+```cpp
+// Demonstrates pop_back()
+#include <iostream>
+#include <list>
+
+int main(){
+    //declare an empty list
+    std::list<int> mylist;
+
+    //append elements to the list
+    mylist.push_back(1);
+    mylist.push_back(2);
+    mylist.push_back(3);
+
+    //print list elements
+    std::cout << "List elements before pop_back()" << std::endl;
+    for (auto element : mylist) {
+        std::cout << element << " ";
+    }
+    std::cout << std::endl;
+
+    //pop element from the back
+    mylist.pop_back();
+
+    //print list elements
+    std::cout << "List elements after pop_back()" << std::endl;
+    for (auto element : mylist) {
+        std::cout << element << " ";
+    }
+
+    return 0;
