How to delete last element from a List in C++ STL
Suppose we have one STL list in C++. There are few elements. We have to delete the last element from that list. So if the elements are like [10, 41, 54, 20, 23, 69, 84, 75], then last element is 75. We will see the C++ code to delete last element from list.
Example
#include<iostream>
#include<list>
using namespace std;
void display(list<int> my_list){
for (auto it = my_list.begin(); it != my_list.end(); ++it)
cout << *it << " ";
}
int main() {
int arr[] = {10, 41, 54, 20, 23, 69, 84, 75};
int n = sizeof(arr)/sizeof(arr[0]);
list<int> my_list;
for(int i = 0; i<n; i++){
my_list.push_back(arr[i]);
}
cout << "List before delete: ";
display(my_list);
my_list.pop_back();//delete last element
cout << "\nList after delete: ";
display(my_list);
}Output
List before delete: 10 41 54 20 23 69 84 75 List after delete: 10 41 54 20 23 69 84
