How do I use the erase function with std::vector in C++?

The erase function in std::vector is used to remove elements from the vector. You can erase elements by their position or by value.

Can you show me an example of erasing an element by position?

Sure! If you have a vector like std::vector<int> vec = {1, 2, 3, 4, 5};, you can erase the element at index 2 (which is 3) using vec.erase(vec.begin() + 2);.

What if I want to erase all occurrences of a specific value?

To erase all occurrences of a value, you can use the remove algorithm followed by erase. For example: vec.erase(std::remove(vec.begin(), vec.end(), value), vec.end());.
