C++ String Data Types

String Types

The string type is used to store a sequence of characters (text). This is not a built-in type, but it behaves like one in its most basic usage. String values must be surrounded by double quotes:


string greeting = "Hello";
cout << greeting; 

To use strings, you must include an additional header file in the source code, the <string> library:


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

int main() {
  string greeting = "Hello Raj";
  cout << greeting;
  return 0;

// Output---> Hello Raj
