insert vector

To insert an element into a vector in C++, follow these steps:

1. Declare a vector variable: Start by declaring a vector variable of the desired type. For example, to create a vector of integers, you can use the following syntax:

std::vector<int> myVector;

1. Push back the element: To insert an element into the vector, you can use the push_back() function. This function adds an element to the end of the vector. For example, to insert the value 10 into the vector, you can use the following code:

myVector.push_back(10);

1. Access the inserted element: To access the inserted element, you can use the vector's index. The index starts at 0, so the first element can be accessed using myVector[0]. For example, to print the value of the inserted element, you can use the following code:

std::cout << myVector[0] << std::endl;

That's it! Following these steps will allow you to insert an element into a vector in C++. Let me know if you have any further questions.
