Answer:
Changing the customer number on a record in the Orders table to a number that does not match a customer number in the customer table would violate referential integrity.
If deletes do not cascade, deleting a customer that has orders would violate referential integrity.
If deletes cascade, customer can be deleted and all orders for that customer will automatically be deleted.
Answer:
The code is given in C++ below
Explanation:
#include <iostream>
using namespace std;
int main()
{
float fv,pv,r,k,n,pmt,totalmoneyinvested;
pv=1000.00;
r=6/100;
k=12; //The value of k should be 12 for monthly installments
n=45;
pmt=250;
totalmoneyinvested=pv+(pmt*12*45); //The total money you invested
fv=pv*(1+r/k)*n*k+pmt*((1+r/k)*n*k-1)*(1+r/k)*r/k;
cout<<"Initial Investment:"<<" $"<<pv;
cout<<"\nRate Of Return:6%";
cout<<"\nLength of Time:"<<n<<"year";
cout<<"\nMonthly Payment:"<<" $"<<pmt;
cout<<"\nFinal Amount:"<<" $"<<fv;
cout<<"\nThe Money You Invested Is $"<<totalmoneyinvested<<" And The Final Amount Is $"<<fv;
return 0;
}
Answer:
import java.lang.Object
import java.lang.Math
public class RegularPolygon extends java.lang.Object{
public void randomize(RegularPolygon c){
int min = 10, max1 = 20;
double min1 = 5, max1 = 12;
double range = (max - min) + 1;
double range1 = (max1 -min1) + 1
int side = (Math.random() * range) + min;
double len = (Math.random() * range1) + min1;
c.setNumSides(side);
c.setSideLength( len);
}
public static void main(String[] args) {
RegularPolygon r = new RegularPloygon();
randomize(r);
}
}
Explanation:
The randomize method accepts a regular polygon class as its only parameter and assigns a random number of sides and the length of these sides with the 'Math.random' function.
The correct option to this question is class interface.
The class interface is the portion of a class that is visible to the application’s programmer. Class interfaces mean implementation of public methods of the class. These class interfaces of the class are easily visible to the application’s program either the one who is developing the application program or the one who is reading the application’s code.
Class interface can be seen by the other classes as its public face. Class interfaces separate the class’s implementation and its interaction with other classes. That way the implementation of the class can be modified easily without being known by other classes. Basically, the programmer who is developing the program, all the portions of the programm is visible to that programmer.
For example, the class is written below:
class class-name
{
private members;
public method()
{
//method defination
}
}
when the class object is created, the code of the object to the programmer is visible.
<u>While the other options are incorrect:</u>
- Form: the form is used to collect information from the user. It can be build using front-end development tools
- Design: Design is a term used in computer or software engineering to make something from scratch or beginning. It can be methodologies, standards, or techniques etc.
- Control: Control is the mechanism or a term used in software development to control the program or execution of the program.
