Printing string capacity function in C++

This C++ code defines a string str and initializes it with the value "TutorJoe's is a Coaching centre". It then prints out the initial value of the string and its capacity using cout.

Here's a step-by-step breakdown of what happens in the code:

The iostream and string.h headers are included to allow input and output and to use strings respectively.
The using namespace std; statement is included to avoid having to use std:: before all standard library functions and types.
A string is defined, str, initialized with the value "TutorJoe's is a Coaching centre".
The initial value of str is printed to the console using cout.
The capacity() method is called on str, which returns the current capacity of the string. The capacity of a string is the amount of memory that has been allocated for it. In this case, it will depend on the implementation of the string class and the size of the string itself.
The value of the capacity of str is printed to the console using cout.
The main() function returns 0, indicating successful completion.

When the code is run, it should print out the initial string value and the capacity of the string to the console. The capacity of the string will depend on the implementation and the size of the string.

Source Code

#include<iostream>
#include<string.h>
using namespace std;
int main()
{
    string str = "TutorJoe's is a Coaching centre";
    cout<<"\nThe Initial string is : ";
    cout<<str<<endl;
    cout<<"\nThe capacity of string is : ";
    cout<<str.capacity()<<endl;
    return 0;
}
