History of the Strings

Earlier in C language the string data type support was not there. For storing the strings we need to use the "char" datatype array which usually ends with a special character '\0'. Therefore, the size of a character array is always one more than that of the string it is stored. This thing is being supported by C++ also but in addition to that the C++ language also has the inbuilt library string which has some extra functions for string manipulation.

char str[] = "Hashnode";
char str[9] = "Hashnode";
char str[] = {'H','a','s','h','n','o','d','e','\0'};
char str[9] = {'H','a','s','h','n','o','d','e','\0'};

Let's look at some examples for getting a better understanding of the string representation in c++ using C - Style.

// C++ program to demonstrate strings using C style

#include <iostream>
using namespace std;

int main()
{

    // Declare and initialize string
    char str[] = "Hashnode";

    // Print string
    cout << str;

    return 0;
}
