Question

C++ Create a program that tells the user if the integer is a prime number or not. Please do not use flag or bool.

Answer #1

**Check the integer
is a prime number or not without using flag or
boolean:**

**code:**

**#include <iostream>
using namespace std;**

**int main() {
int i, n; /* variable declaration */
cout <<"Enter a positive integer: ";
cin >> n; /* take user input */
// 0 and 1 are not prime numbers
if (n == 0 || n == 1) {
cout<<n<<" is not prime"<<endl;
}
else {
for (i = 2; i<n; ++i) { /* run the loop 2 to n */
if (n % i == 0 && i!=n) {
cout<<n<<" is not prime"<<endl;
break;
}
}
}
if (i==n)
cout << n << " is a prime number"; /* print the
output*/**

**return 0;
}**

**output
screen:**

//if you have a any doubt please comment ...........

Write a C++ program that asks the user to enter an integer
number and prints it back "vertically" to the screen. Use recursion
in your solution. As an example of how the program will work:
Please enter an integer: 12345
The integer you entered will print vertically as:
1
2
3
4
5

/*
This program should check if the given integer number is
prime.
Reminder, an integer number greater than 1 is prime if
it divisible only by itself and by 1.
In other words a prime number divided by any other natural
number
(besides 1 and itself) will have a non-zero remainder.
Your task:
Write a method called checkPrime(n) that will
take
an integer greater than 1 as an input, and return true
if that integer is prime; otherwise, it should...

A prime number (or a prime) is an integer greater than
1 that is not a product of two smaller integer. Created a program
on visual studio named PrimeNumberTest that does
the following:
1) prompt the user for input of an integer
2) test if the integer is a prime number
3) display the test result

Create a flowchart that asks the user to enter a number. (Assume
this number is integer!) If the number is multiple of 5 then show a
message that says “HiFive”. If the number is multiple of 3 then
show a message that says “HiThree”. If the number is multiple of 2
then show a message that says “HiTwo”. Then end the Flowchart.
(Tip: Use the % symbol for modulus operation) (Tip2: If the number
is not a multiple of 5,...

Write a program that prompts the user to input a positive
integer. It should then output a message indicating whether the
number is a prime number.
(Note: An even number is prime if it is 2. An odd integer is prime
if it is not divisible by any odd integer less than or equal to the
square root of the number.)

Use C++ to implement the following program
about Prime Factorization of a Number. Do BOTH
parts of the problem or you will lose points. Provide
comments to explain each step.
a. Write a function that takes as a parameter a positive integer
and returns a list (array) of the prime factors of the given
integer. For example, if the parameter is 20, you should return 2 2
5.
b. Write a function that tests the above function by asking the...

design a program that prompts the user to enter a positive
integer number and reads the user’s input. If the user input is not
a positive number, the program should prompt them repeatedly until
they enter a valid input. Once a valid input is received ,the
program uses a loop to calculate the sum of the digits of the
user’s input and displays the sum. For example, if the user enters
the number 94311, the program should print the sum...

Write a program that prompts
the user to enter an integer number between 1 and 999. The program
displays the sum of all digits in the integer if the input is
valid; otherwise, it displays a message indicating that the integer
is not between 1 and 999 and hence, is invalid.
Name the program file Q1.cpp
Example: if the user enters 12, sum of digits is
3.
If the user enters 122, sum of digits is 5.

Write a function called "isPrime()” that checks if an integer
number is prime or not. The function returns integer 1 if the
number is prime, or integer 0 if the number is not prime. Write a
simple test program in main() to show that the function works
properly.in C programming language.

The Java program should sum the odd integers from 1 to the
integer that the user enters. For example, if the user enters 30,
the program should sum the odd integers from 1 to
30.
Print "Please enter a positive nonzero integer."
Declare a Scanner and obtain an integer from the
user.
Use a Do...while statement and
calculate the sum
Use the integer that the obtained from the previous step for
the loop-continuation condition.
Display the sum
Print the sum...
