In the following code, no delimiter ("") is specified to print the string in its original form. Example Code: #include <iostream> #include <iterator> #include <string> #include <vector> using std::cin; using std::copy; using std::cout; using std::endl; using std::string; using ...

In this example, the user must input two numbers. Then we print the sum by calculating (adding) the two numbers:Example int x, y;int sum;cout << "Type a number: ";cin >> x;cout << "Type another number: ";cin >> y;sum = x + y;cout << "Sum is: " << sum; Run ...

Another better solution/algorithm to avoid concatenation of string in every recursive call is to use another parameter that will take input i as an integer such that the function will give the reverse of the string starting from the index i to the end of the string. ...
