Question

Hello, one of the assignment questions is to add a Vector, This is my assignment below. Can someone add a Vector so i can see how a Vector code looks like. thank you. this code is C++

Explanation / Answer

Vectors in C++

vectors are basically arrays that can changes size dynamically and can be of any type.

vectors use a dynamically allocated array to store their elements.

Vector is a derived from class Template

lets try to learn vector by various examples:

#include<vector> //header file

std::vector<int > v; // declare a vector of int

or

using namespace std;

vector<char> v; //declare a vector of charactor

v.push_back(cnt); // to input a element in vector

v.size() // to return size of vector

v[0] // to use first element of vector.

v.pop_back(); // delete last element

v.resize(10); //resize the vector

v.begin() and v.end() :- return iterator to begining and end

Now you have learned the methods of vector class, take a look on this sample program for more understanding:

*** In your code you can change these two defination to vectors

double ToppingsPrice[4] = { .25, .50, .75, .10 };

vector<double> ToppingPrice[4]

string Flavors[2][3] = { { "Chocolate", "Strawberry", "Vanilla" },{ "Banana", "Cherry", "Pineapple" } };

you can now use these variables for further operations normally.
