Use the variables k, d, and s so that they can read three different values from standard input--an integer, a double, and a string respectively. on one line, print these variables in reverse order with exactly one space in between each. on a second line, print them in the original order with one space in between them.

The c++ program to implement the given scenario is shown below.

#include <iostream>

using namespace std;

int main() {

   // variables declared as mentioned

   int k;

   double d;

   string s;

   cout << " Enter an integer value, a double value, a string value in the mentioned order " << endl;

   cin >> k >> d >> s;

   // variables printed in reverse order

   cout << " Reverse order " << endl;

   cout << s << " " << d << " " << k << endl;

   // variables printed in original order

   cout << " Original order " << endl;

   cout << k << " " << d << " " << s << endl;

   return 0;

}

OUTPUT

Enter an integer value, a double value, a string value in the mentioned order  

12 45.67

Reverse order  

45.67 12

Original order  

12 45.67

Explanation:

1.All the variables are declared as mentioned in the question.

int k;

   double d;

   string s;

2.The user is prompted to enter values for integer, double and string variables respectively. The input is accepted in the order mentioned above.

cin >> k >> d >> s;

3.The input is accepted in a single line since this is mentioned in the scenario that variables should be printed in the order in which they are read.

4.These variables are displayed to the standard output in reverse order – string, double, integer. The variables are displayed with exactly one space in between them.

cout << s << " " << d << " " << k << endl;

5.Then, variables are displayed in the original order – integer, double, string. The variables are displayed with exactly one space in between them.

cout << k << " " << d << " " << s << endl;

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
