  Objective In this challenge, we practice reading input from stdin and printing output to stdout. In C++, you can read a single whitespace-separated token of input using  cin , and print output to stdout using  cout . For example, let's say we declare the following variables: string s ; int n ; and we want to use  cin  to read the input "High 5" from stdin. We can do this with the following code: cin >> s >> n ; This reads the first word ("High") from stdin and saves it as string  , then reads the second word (" ") from stdin and saves it as integer  . If we want to print these values to stdout, separated by a space, we write the following code: cout << s << " " << n << endl ; This code prints the contents of string  , a single space ( ), then the integer  . We end our line of output with a newline using  endl . This results in the following output: High 5 Task Read   numbe...
