Initialize Vector Iterator with begin() function

To initialize a vector iterator with the begin() function in C++, follow these steps:

1. Include the necessary header file: #include <vector>
2. Declare a vector of a specific type: std::vector<int> myVector;
3. Add elements to the vector if needed: myVector.push_back(10);
4. Initialize the iterator using the begin() function: std::vector<int>::iterator it = myVector.begin();
5. Use the iterator to access elements of the vector: int firstElement = *it;

I hope this helps!
