Updating vector elements in C++

The entries of vectors are mutable and can be changed freely, using indices and the bracket notation, just like we do with static arrays:

vector<string> names = {"Andy", "Mary", "Cody"};

names[0] = "Mircea";
names[2] = "Mike";

// names is now {"Mircea", "Mary", "Cody"}
