The programing language, R has a unite unite function in the tidyr package. Hence, the code chunk which let's the analyst create the location column is; <em>unite (stores, "location”, city, state, sep=",") </em>
- The syntax for the unite function is ; unite(data,col,..., sep)
- <em>data</em><em> </em><em>=</em><em> </em><em>dataframe</em><em> </em><em>from</em><em> </em><em>which</em><em> </em><em>data</em><em> </em><em>is</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>extracted</em><em> </em><em>`</em><em>;</em><em> </em>stores
- <em>col</em><em> </em><em>=</em><em> </em><em>name</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>new</em><em> </em><em>column</em><em> </em><em>;</em><em>"</em><em> </em>location"
- <em>.</em><em>.</em><em>.</em><em> </em><em>=</em><em> </em><em>dataframes</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>merged</em><em> </em><em>;</em><em> </em>city, state
- <em>sep</em><em> </em><em>=</em><em> </em><em>seperator</em><em> </em><em>;</em><em> </em>","
Hence, the required syntax goes thus :
- unite (stores, "location”, city, state, sep=",")

Answer:
import java.util.Scanner;
public class num2 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int total = 0;
for(int i=0; i<5; i++){
System.out.println("Enter next Int: ");
total = total+in.nextInt();
}
System.out.println(total);
}
}
Explanation:
In the code above written in Java programming language, the for loop statement for(int i=0; i<5; i++) ensures that the loop goes from 0-4 a total of five times.
At each iteration it requests a user to enter an int. The number entered is stored in the variable total which is initially assigned 0.
When the loop finishes execution, total is printed out
