1st question:
Use the variables k, d, and s so that they can read three different values from standard input an integer, a float, 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.
Solution:
In Python:
k = input() #prompts user to input value of k i.e. integer value
d = input() #prompts user to input value of d i.e. float value
s = input() #prompts user to input value of s i.e. a string
print (s, d, k) #displays these variable values in reverse order
print (k, d, s)#displays these variable values in original order
In C++:
#include <iostream> // to use input output functions
using namespace std; //to identify objects like cin cout
int main() { //start of main function
int k; //declare int type variable to store an integer value
float d; // declare float type variable to store a float value
string s; // declare string type variable to store an integer value
cin >> k >> d >> s; //reads the value of k, d and s
cout << s << " " << d << " " << k << endl; //displays these variables values in reverse order
cout << k << " " << d << " " << s << endl; } // displays these variable values in original order

2nd question:
You would like the user of a program to enter a customer’s last name. Write a statement that asks user "Last Name:" and assigns input to a string variable called last_name.
Solution:
In Python:
last_name = input("Last Name:")
# input function is used to accept input from user and assign the input value to last_name variable
In C++:
string last_name; //declares a string type variable named last_name
cout<<"Last Name: "; // prompts user to enter last name by displaying this message Last Name:
cin>>last_name; // reads and assigns the input value to string variable last_name
The programs alongwith their outputs are attached.
Answer:
Here is the CoordTransform() function:
void CoordTransform(int xVal, int yVal, int &xValNew, int &yValNew){
xValNew = (xVal + 1) * 2;
yValNew = (yVal + 1) * 2; }
The above method has four parameters xVal and yVal that are used as input parameters and xValNew yValNew as output parameters. This function returns void and transforms its first two input parameters xVal and yVal into two output parameters xValNew and yValNew according to the formula: new = (old + 1) *
Here new variables are xValNew and yValNew and old is represented by xVal and yVal.
Here the variables xValNew and yValNew are passed by reference which means any change made to these variables will be reflected in main(). Whereas variables xVal and yVal are passed by value.
Explanation:
Here is the complete program:
#include <iostream>
using namespace std;
void CoordTransform(int xVal, int yVal, int &xValNew, int &yValNew){
xValNew = (xVal + 1) * 2;
yValNew = (yVal + 1) * 2;}
int main()
{ int xValNew;
int yValNew;
int xValUser;
int yValUser;
cin >> xValUser;
cin >> yValUser;
CoordTransform(xValUser, yValUser, xValNew, yValNew);
cout << "(" << xValUser << ", " << yValUser << ") becomes (" << xValNew << ", " << yValNew << ")" << endl;
return 0; }
The output is given in the attached screenshot
