How do you modify the values of elements in a vector?

To change the value of an element in a vector, you can use the subscript operator [], specifying the index of the element to be modified. For example, if there is a vector named vec and we want to modify the third element to be 5, we can use the following code:

Assign the value of 5 to the element at index 2 in the vector.

This will change the third element in the vector to 5. Please note that vector indexing starts at 0, so the index of the third element is 2.
