iteraate through a vector

To iterate through a vector in C++, you can use a range-based for loop or a regular for loop. Here's an example using a range-based for loop:

#include <iostream>
#include <vector>

int main() {
  std::vector<int> myVector = {1, 2, 3, 4, 5};

  for (int element : myVector) {
    std::cout << element << " ";
  }

  return 0;
}

Here's an explanation of each step:

1. We include the necessary header files, <iostream> and <vector>, which provide the necessary functionalities for input/output and vectors respectively.

2. We declare the main function.

3. We create a vector called myVector and initialize it with some values.

4. We use a range-based for loop to iterate through each element in the vector. The loop variable element takes on the value of each element in myVector in each iteration of the loop.

5. Inside the loop, we print the value of element followed by a space.

6. Finally, we return 0 to indicate successful program execution.

When you run this program, it will output:

1 2 3 4 5

This demonstrates how to iterate through a vector in C++ using a range-based for loop.
