How to Copy a Vector to an Array in C++? Last Updated : 18 Mar, 2024 Comments Improve Suggest changes Like Article Like Report In C++, vectors are dynamic arrays that can grow and reduce in size as per requirements. Sometimes, we may need to copy the contents of a vector to the POD array. In this article, we will learn how to copy a vector to an array in C++. Example: Input: myVec = {10,20,30,40,50,60};Output: array: {10,20,30,40,50,60}Convert Vector to an Array in C++ For copying the elements stored in a std::vector to an array in C++, we can use the std::copy() function provided in the STL <algorithm> library that copies a range of elements from one container to another. Syntax to of std::copy()copy (first, last, result);Here, first is the iterator to the beginning of the vector.last is the iterator to the end of the vector.result is the iterator to the beginning of the array.C++ Program to Copy a Vector to an ArrayThe below program demonstrates how we can copy a vector to an array using copy() in C++. C++ // C++ program to illustrate how to copy a vector to an // array #include <algorithm> #include <iostream> #include <vector> using namespace std; // Driver code int main() { // Vector vector<int> vec = { 10, 20, 30, 40, 50, 60 }; // Print the vector cout << "Vector: "; for (int i = 0; i < vec.size(); i++) cout << vec[i] << " "; cout << endl; // Array to store the vector elements int arr[vec.size()]; // Copy vector to array copy(vec.begin(), vec.end(), arr); // Print the array cout << "Array: "; for (int i = 0; i < vec.size(); i++) cout << arr[i] << " "; cout << endl; return 0; } OutputVector: 10 20 30 40 50 60 Array: 10 20 30 40 50 60 Time Complexity: O(N), here N is the size of the vector.Auxiliary Space: O(1) Comment More infoAdvertise with us Next Article How to Copy a Vector to an Array in C++? vishaldhaygude01 Follow Improve Article Tags : C++ Programs C++ STL cpp-array cpp-vector CPP Examples +2 More Practice Tags : CPPSTL Similar Reads How to Convert an Array to a Vector in C++? In this article, we will learn how to convert the given array into vector in C++.The simplest method to convert an array to vector is by using range constructor of vector. Letâs take a look at an example:C++#include <bits/stdc++.h> using namespace std; int main() { int arr[] = {1, 3, 6, 2, 9}; 3 min read How to Create a Vector of Arrays in C++? In C++, an array is a collection of elements of a single type while vectors are dynamic arrays as they can change their size during the insertion and deletion of elements. In this article, we will learn how to create a vector of arrays in C++. Example: Input: arr1 = {1, 2, 3}; arr2 = {4, 5, 6}; arr3 2 min read How to Copy One Array to Another in C++? In C++, arrays are a type of data structure that stores a fixed-size collection of elements of the same type in a contiguous memory location, and sometimes we need to copy the contents of one array to another. In this article, we will learn how to copy one array to another in C++. Example: Input: ar 2 min read How to Loop Over an Array in C++? In C++, an array is a data structure that stores elements of similar type in contiguous memory locations. We can access the elements of an array using array indexing. In this article, we will learn how to loop over an array in C++. Example: Input: int arr[] = [1, 2, 3, 4, 5] Output: Array Elements: 2 min read How to Initialize Vector of Char Arrays in C++? In C++, a vector is a dynamic array that can grow and shrink in size. A char array is a sequence of characters, typically used to represent strings.
