Answer:
Program is written in C++
#include<iostream>
using namespace std;
int main()
{
//1. Prime Number
int num;
cout<<"Input Number: ";
cin>>num;
int chk = 0;
for(int i =2; i <num;i++)
{
if(num%i==0)
{
chk = 1;
break;
}
}
if(chk == 0)
{
cout<<num<<" is prime"<<endl;
}
else
{
cout<<num<<" is not prime"<<endl;
}
//2. Greatest Common Factor
int num1, num2, x, y, temp, gcf;
cout<<"Enter two numbers: ";
cin>>num1;
cin>>num2;
x = num1;
y = num2;
while (y != 0) {
temp = y;
y = x % y;
x = temp;
}
gcf = x;
cout<<"Greatest Common Factor: "<<gcf<<endl;
// 3. LCM
cout<<"Enter two numbers: ";
cin>>num1;
cin>>num2;
x = num1;
y = num2;
while (y != 0) {
temp = y;
y = x % y;
x = temp;
}
gcf = x;
int lcm =(num1 * num2)/gcf;
cout<<"Least Common Multiple: "<<lcm<<endl;
return 0;
}

Verbal language because somebody's verbal words are more receptive then ones written word
Answer and Explanation:
The ways in which a layered pattern make use of encapsulation and abstraction are as follows:
- This framework lays its focus mainly on the bundling of related functionalities inside an application into different layer that are vertically stacked over one another.
- Functionality in between each layer is related by common function or role.
- Communication in between the layers is clear and exact and is coupled loosely.
- Providing a layered structure to the application indirectly supports its maintainability and flexibility.
Encapsulation:
Since, features like data type, properties, methods or implementation while designing are not exposed at the boundary of the layer thus No assumptions are required for these features.
Abstraction:
The layered framework abstracts the entire system's view and provides adequate details for better understanding of the roles of each layer individually and the relation that exist between these layers.
Answer:
shareware
Explanation:
It is the shareware, which is available for free for a certain period, and after that, the actual fee is charged for continued usage. The public domain is free from copyright, patent or trademark laws, and is the public property. The open-source is the free code of software that is available with code for the whole developer community. And it is shared among all the developers. And the developer can be anybody. The freeware is the software that is provided free of cost by the publisher. And there is no set of rights, licenses or EULA that governs its distribution, and each publisher frames his own set of rules for the usage of the freeware.
