Write a C++ program to exchange values of two variables using function exchange().

Shkiper50 [21]

Answer:

#include<iostream>

using namespace std;

//create the exchange function

void exchange(int a, int b){

int temp; //initialize temporary

//swap the variables value

temp=a;

a=b;

b=temp;

//print the output after exchange

cout<<"a is: "<<a<<endl;

cout<<"b is: "<<b<<endl;

}

//main function program start from here

int main(){

//initialization

int a=3, b=6;

exchange(a,b); //calling the function

return 0;

}

Explanation:

Create the function exchange with two integer parameter which takes the value from the calling function.

and then declare the third variable temp with is used for swapping the value between two variables.

first store the value of 'a' in the temp and then assign the 'b' value to 'a' and then, assign the temp value to b.

for example;

a=2, b=9

temp=2;

a=9;

b=2;

So, the values are swap.

and then print the swap values.

Create the main function and define the input a and b with values.

Then, calling the exchange function with two arguments.

Write a SELECT statement to create a lesson schedule for Feb 1, 2020 with the lesson date/time, student's first and last names,

Fed [463]

SELECT statement are used to retrieve data from a database table

The SELECT statement that creates the lesson schedule is:

<em>SELECT LessonDateTime, HorseID, FirstName, LastName FROM LessonSchedule JOIN Student ON LessonSchedule.StudentID = Student.ID ORDER BY LessonDateTime ASC, HorseID</em>

<h3>How to determine the SELECT statement</h3>

To write the select statement, we start by writing the following query that retrieves Lesson date/time, horse ID, first name, and last name from the lesson schedule table.

So, we have:

SELECT LessonDateTime, HorseID, FirstName, LastName FROM LessonSchedule

Next, the query would confirm the presence of a student ID in the lesson schedule table and the student table using the JOIN statement

JOIN Student ON LessonSchedule.StudentID = Student.ID

From the question, we understand that:

The result should be sorted in ascending order by lesson date/time.

This is represented as:

ORDER BY LessonDateTime ASC, HorseID

Hence, the complete query is:

SELECT LessonDateTime, HorseID, FirstName, LastName FROM LessonSchedule JOIN Student ON LessonSchedule.StudentID = Student.ID ORDER BY LessonDateTime ASC, HorseID
