Create array of strings in C++

Hello, Guys in this tutorial we learn how to create an array of strings in C++. First, we need to understand what is an array. An array is a collection of data elements. These data elements have the same data type. The data type can be of any type, for example, integer, float, character and string etc. Data are stored in a contiguous memory location. An array is an inbuilt data structure.

In C++ we can create an array in many ways-

Creating a static string array in C++

  formate
   
  string name_of_array[size of array];

#include <iostream>
using namespace std;

int main() {
  

  
string str[5]={"i","like","code","speedy","very much"};  //declaring a array of string
  
  for (int i = 0; i < 5; i++) { 
     cout << str[i] <<endl;       //printing a array of string
  }
  
  
  
  return 0;
}

output

i
like
code
speedy
very much

Create a string array  Dynamically in C++

formate

string* name_of_array=new string[size_of_array];

#include <iostream>
using namespace std;

int main() {
  

  
    string* str=new string[5];   //declaring a dynamic array of string
  
  for (int i = 0; i < 5; i++) {
      cin>>str[i];      //taking string as input
  }
  
  for(int i=0;i<5;i++)
  {
      cout << str[i] <<endl;  //printing a string
  }
  
  return 0;
}

Input
the
corner
from
my 
house

Output
the
corner
from
my
house

Create array of strings using Vector in C++

Vector is a dynamic array. It automatically changes its size when element deletes or insert in it. We do not require to enter the size of the vector.

formate

vector<string> name_of_vector

#include <iostream>
#include <vector> 
using namespace std;

int main() {
  
  vector<string> str;  //declaring a vector of string
  
  for(int i=0;i<5;i++)
  {
      string s;
      cin>>s;    //taking string as a input
      
      str.push_back(s);  // push_back fuction is use to insert a element into vector from back
      
  }
  
  for(int i=0;i<5;i++)
  {
      
      cout << str[i] <<endl;  //printing a string array
      
  }
  
  
  return 0;
}

Input
the
corner
from
my 
house

Output
the
corner
from
my 
house
