How do I remove an item from a C++ list?

How do I remove an item from a C++ list?

You can use the remove method from the <list> library. For example, myList.remove(value); will remove all instances of value.

What if I want to remove only the first occurrence?

In that case, you can use the remove method as well, but if you want to ensure only the first occurrence is removed, you might need to use an iterator to find it first.

Can you show me an example code snippet?

Sure! Here's a simple example:

#include <iostream>
#include <list>

int main() {
    std::list<int> myList = {1, 2, 3, 2, 4};
    myList.remove(2); // This removes all occurrences of 2
    for (int n : myList) std::cout << n << ' '; // Outputs: 1 3 4
}
