cout << "----------------------\n";
cout << " Enter a string: ";
getline(cin, str);
cout << " The string in reverse are: ";
revOfString(str);
return 0;
}
void revOfString(const string& str)
{
size_t lengthOfString = str.size();
if(lengthOfString == 1)
cout << str << endl;
else
{
cout << str[lengthOfString - 1];
revOfString(str.substr(0, lengthOfString - 1));
}
}
