The Standard Template Library (STL) includes the collection of data types and
- A special data type called vector is offered by STL which is useful for standard arrays.
A vector stores the elements or values in sequence order and the values are stored in continuous memory locations.
- The subscript operator “[]” in the vector helps to read the content of each element.
Initialization of vector:
In C++, the vector is initialized with the respective value as like the array but it does not use the “=” operator before the list and uses the keyword “vector”.
- The initialization list values are enclosed with the braces.
Consider the following statement:
//Declaring a vector with four values
vector <int> values {40, 32, 15, 17};
In the above line, the keyword “vector” represents the vector declaration, “<int>” represents that the vector holds integer type values, “values” represents the name of the vector, and the values inside the braces refers the values of the vector “values”.

- (C++) Write a stand-alone function (not a class/method) to create a unit vector from a 3D vector. Write the function and a simple structure for the Vector (no methods).arrow_forwardC++ Please Write a program that utilizes a struct data structure and a vector of that structure type. 1. Create an Account struct that includes the following data members: string fName (first name), string IName (last name), string email. 2. Create a vector of type Account called "Accounts". [vector<VectorDataType>vectorName] 3. Create two Accounts acct1 and acct2. Use user-input the get data for the accounts. 4. Add both Accounts to the accounts vector. 5. Use a loop to print every Account in the vector.

- Translator Using as a basis the program that allows to deal cards from a deck to a player's hand, add functionality that allows to update the deck of cards. Updating the deck of cards involves moving the cards from the deck to the beginning of the vector as the player requests a new card. At each deal, the cards in the deck must be printed to make the code in c language. The following functions must be implemented additionally: updateDeck. - This function receives two arguments: a vector with the deck of cards to update and the current size of the deck of cards. It will move the cards in the deck to the beginning of the vector. printVector - This function will receive two parameters: a vector and its dimension. The function will print the vector, and will print the values (the vector) of the initial hand, the updated deck, and the final hand. to make the code in c language Expected output :arrow_forward/* Movie List Example --Showing how to use vectors and structures */ #include <iostream> #include <iomanip> #include <string> #include <vector> using namespace std; // define a struct for a Movie object struct Movie // It is common for the struct name to be capitalized { string title = ""; // First member of structure - and initialized int year = 0; // Second member of structure - and initialized }; int main() { cout << "The Movie List program\n\n" << "Enter a movie...\n\n"; // get vector of Movie objects vector<Movie> movie_list; char another = 'y'; while (tolower(another) == 'y') { Movie movie; // make temporary new (initialized) Movie object cout << "Title: "; getline(cin, movie.title); cout << "Year: "; cin >> movie.year; movie_list.push_back(movie);…arrow_forward/* Movie List Example --Showing how to use vectors and structures */ #include <iostream> #include <iomanip> #include <string> #include <vector> using namespace std; // define a struct for a Movie object struct Movie // It is common for the struct name to be capitalized { string title = ""; // First member of structure - and initialized int year = 0; // Second member of structure - and initialized }; int main() { cout << "The Movie List program\n\n" << "Enter a movie...\n\n"; // get vector of Movie objects vector<Movie> movie_list; char another = 'y'; while (tolower(another) == 'y') { Movie movie; // make temporary new (initialized) Movie object cout << "Title: "; getline(cin, movie.title); cout << "Year: "; cin >> movie.year; movie_list.push_back(movie);…arrow_forward
- In GO language. Create a struct that has student name, id, and GPA. Write functions to create a student, modify the student’s id, and modify the student's GPA, and print the student’s information. (This is like creating a class and methods). Now create an array of three students and test your functions. You may hardcode your values if using a web conpiler. (Please hardcode the values!)arrow_forwardIf integer pointer aPtr is to point at a data item whose value may not change it must be declared as ...
