How to use the Array Class In C++

Q: How to use the Array Class In C++

The STL string or string class may be used to create an array of mutable strings. In this method, the size of the string is not fixed, and the strings can be changed which somehow makes it dynamic in nature nevertheless std::string can be used to create a string array using in-built functions.

4. Using the vector class

An array is a homogeneous mixture of data that is stored continuously in the memory space. The STL container array can be used to allocate a fixed-size array. It may be used very similarly to a vector, but the size is always fixed.

Example:

C++

// C++ program to demonstrate 
// array of string using STL array
#include <array>
#include <iostream>
#include <string>
 
// Driver code
int main()
{
  // Initialize array
  std::array<std::string, 4> colour{"Blue", "Red",
                                    "Orange", "Yellow"};
 
  // Printing Strings stored in array
  for (int i = 0; i < 4; i++)
      std::cout << colour[i] << "\n";
 
  return 0;
}

Output

Blue
Red
Orange
Yellow

These are by no means the only ways to make a collection of strings. C++ offers several container classes, each of which has various tradeoffs and features, and all of them exist to fill requirements that you will have in your projects. Explore and have fun!

Conclusion: Out of all the methods, Vector seems to be the best way for creating an array of Strings in C++.

Array of Strings in C++ – 5 Different Ways to Create

In C++, a string is usually just an array of (or a reference/points to) characters that ends with the NULL character ‘\0‘. A string is a 1-dimensional array of characters and an array of strings is a 2-dimensional array of characters where each row contains some string.
