string lastName = "Babu";

You can also change any individual character of a string in C++.

string variable1 = "Hello World";
variable1[1] = 'i';
cout << variable1;

string variable1 = "Find my length";
cout << "The length of the string is: " << variable1.length();

It returns the length of the string as an integer.
