	name [5] = 'e' ; // initialize the 5th element of the string
	for (int i=0 ; i<5 ; i++)
	{
		name  += ' ';  //putting spaces from element 0 to 4 in the string
	}
        // print the string till the 5th element

	string name ;
	cout << "Length of string is: " << name.length() << endl;

Output:
Length of string is: 0

It doesn't make sense to access elements outside the string, such as name[5].
