g Design a Boolean function called isPrime, that accepts an integer as an argument and returns True if the argument is a prime n

professor190 [17]

Answer:

#include <bits/stdc++.h>

using namespace std;

bool isPrime(int n)

{

for(int j=2;j<=n-1;j++) //loop to check prime..

{

if(n%j==0)

return false;

}

return true;

}

int main(){

int n;

cout<<"Enter the integer"<<endl;//taking input..

cin>>n;

if(isPrime(n))//printing the message.

{

cout<<"The number you have entered is prime"<<endl;

}

else

{

cout<<"The number is not prime"<<endl;

}

return 0;

}

Output:-

Enter the integer

The number you have entered is prime

Explanation:

The above written program is in C++.I have created a function called isPrime with an argument n.I have used a for loop to check if the number is prime or not.In the main function I have called the function isPrime for checking the number is prime or not.

Why are computer simulations useful in studying phenomena in the universe?

amid [387]

Answer:

Explanation:

Computer simulations are helpful because they can handle the computation of a big number of variables, at the same time. The universe is a constantly changing place with many different variables changing other variables. Thus, a computer is ideal to simulate, or predict, real life phenomena because of its processing power.

Alenkinab [10]

1.
#include <iostream>#include <string>
using namespace std;
int main(){ string chars; // This is where we will put our @ signs and print them for(int x=0;x < 5; x++){
chars = chars + '@'; // This will concatenate an @ sign at the end of the variable cout << chars << "\n"; }}

2.
#include <iostream>#include <string>
using namespace std;
int main(){ string name; // Our variable to store the name cout << "What is your name? \n"; // Asks the user for their name cin >> name; cout << "\nWell, hello " << name << "!";}

3.
#include <iostream>#include <string>
using namespace std;
int main(){ int number; // Our variable cout << "Enter a number\n"; // Asks for a number cin >> number; cout << "You entered " << number << "%!";}

4.
#include <iostream>#include <string>
using namespace std;
int main(){ int number; // Our variable cout << "Enter a number\n"; cin >> number;
int check = number % 2; // The modulo operator (the percent sign) gets the remainder of the quotient if (check == 0) { cout << number << " is even!"; // If the remainder is 0 then it prints out "x is even" } else { cout << number << " is odd!"; // If the remainder is not 0 then it prints out "x is odd" }}

5.
#include <iostream>#include <string>
using namespace std;
int main(){ float r; // Our variable cout << "Enter a radius\n"; cin >> r; if (r < 0){ cout << "Lol. No."; // If the radius is less than zero print out that message } float circumference=2*3.14*r; float area=r*r*3.14; cout << "\n\n Circumference of circle: " << circumference; cout << "\n Area of circle: " << area;}

public static void main(String ar[]) //define main function

{

String Name,hobby,dream_Job; //declare variable.

int age;

Scanner sc = new Scanner(System.in); //creating Scanner class object for user input.

System.out.print("Enter Your Name : "); //message

name = sc.next(); //user input

System.out.print("Enter Your Age : ");

age = sc.nextInt();

System.out.print("Enter Your hobby: ");

hobby = sc.next();

System.out.print("Enter Your aim: ");

aim = sc.next();

//print values.

System.out.println("Hello, my name is "+name+" and I am "+age);

System.out.println("years old.My hobby is playing "+hobby+".");

}

Output:

Hello, my name is XXX and I am 21

years old.My hobby is playing cricket .

I want to be a cricketer when I grow up!.

Explanation:

In the above program firstly we import the package for user input. Then we declare a class that is Person_detail. In this class, we declare the main function. In the main function, we declare a variable that is name, hobby, aim, and age. In these variable first 3 variables datatype is string and age variable data type in integer. Then we create a scanner class object and take input from the user and print it into a paragraph.
