Should I always call vector clear() at the end of the function?

Question

I have some simple function that uses vector like this (pseudo code):

void someFunc(void) {

    std::vector contentVector;

    // here a

Since I don't think anyone else has mentioned this, but if your vector was

std::vector vector;

you should free the memory allocated to each element before the function finishes (unless you've passed ownership to somewhere else - such as a global variable etc)

for (auto i : vector) {
  delete i;
}
