Description: Remove all current elements of the vector, reducing its size to 0.
Example:
std::vector<int> myVector;
// Initialize vector with the values {1,2,3,4,5}
myVector = {1,2,3,4,5};
// Output: "1 2 3 4 5"
for (int i : myVector) {
std::cout << i << " ";
}
std::cout << std::endl;
// Size of vector is 5
std::cout << "Vector size: " << myVector.size() << std::endl;
// Clear the vector of all values, myVector now contains no values
myVector.clear();
// Output is blank
for (int i : myVector) {
std::cout << i << " ";
}
std::cout << std::endl;
// Size of vector is 0
std::cout << "Vector size: " << myVector.size() << std::endl;
