How can I modify STL vectors in C++?

You can modify STL vectors in C++ using various methods like push_back, pop_back, insert, and erase.

Can you give me an example of using push_back?

Sure! You can use push_back to add an element to the end of a vector like this:

std::vector<int> vec;
vec.push_back(10);

What about removing an element?

To remove an element, you can use pop_back to remove the last element or erase to remove a specific one. For example:

vec.pop_back(); // removes the last element
vec.erase(vec.begin() + 1); // removes the second element

Are there any other useful functions for STL vectors?

Yes! Functions like size(), clear(), and resize() are also very useful for managing STL vectors.
