declaring strings c++

std::string str = "hello world"; 
char *str = "hello world";
char str[] = "hello world"; 
char str[11] = "hello world"; 

string in cpp

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

int main() 
{
  string helloWorld = "Hello World!"; // creating string and assigning
  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++

	string x = "Hello", y = "World";

	y.assign(x);
	cout << "y= " << y << endl;
	cout << "First character in x= " << x.at(0) << endl;
	cout << "Length of string= " << x.length() << endl; 
	cout << "length of string= " << x.size() << endl;			//better than .length
	cout << "Substring of x: " << x.substr(3) << endl;
	 				//or
	cout << "Substring of x: " << x.substr(0,3) << endl;
	cout <<"Before swapping: " << x << " " << y << endl;
	x.swap(y);
	cout << "After swapping: " << x << " " << y << endl;
	cout << "position of the character	He: " << x.find("He") << endl;
	cout << "position of the second l: " << x.rfind("l") << endl;//make the searching operation from right to left
	cout << x.erase(0,3) << endl;		//delete from index 0 to less than 0
				//or
	cout << x.erase(3) << endl;
	cout << x.replace(5,3,"early") << endl;
				//or
	cout << x.replace(x.find("e"),3,"ali") << endl;

	cout << x.insert(1, "new") << endl;

string in C++

#include <iostream>
#include <string>

int main(){
	std::string name = "Eria";
    std::cout <<name;
}

string in c++

#include <bits/std.hc++>
using namespace std;

int main(){
 	string word = {"Hi  this my account on instgram 0.wht"};
  	cout<<word<<endl;
  
 return 0;
}

c++ write string

#include <iostream>

int main() {
	std::cout << "Hello" << std::endl; //endl = end line/new line
    // or
    printf("hello");
    
}

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;    
}
