string in cpp

// you want to include <string>
#include <string>
#include <iostream>

int main() 
{

  std::cout << helloWorld;            // will output what you assigned it!
                                      /* you can also use strings with user 
                                      input (cin/getline)*/
  string namePerson{};
  getline(cin, namePerson); // getline allows for multi word input
  std::cout << namePerson;  // outputs name which person inputted
}

string c++

#include <string>
std::begin		| returns an iterator to the beginning of a container 
std::end		| returns an iterator to the end of a container 
std::size		| returns the length of string
std::to_string	| converts a number to string
std::stoi		| converts a string to a signed integer
std::getline 	| read data from an I/O stream into a string
std::swap  		| specializes the std::swap algorithm
std::empty 		| checks whether the container is empty

C++ String Example

#include <iostream>  
using namespace std;  
int main( ) {  
        string one = "Welcome to";    
        char ch[] = { 'S', 'o', 'f', 't', 'h', 'u', 'n', 't'};    
        string two = string(ch);    
        cout<<one<<endl;    
        cout<<two<<endl;    
}
