Question

A prime number is an integer greater than 1 that is evenly divisible by only 1 and itself. For example, 2, 3, 5, and 7 are prime numbers, but 4, 6, 8, and 9 are not. Create a PrimeNumber application that prompts the user for a number and then displays a message indicating whether the number is prime or not. Hint: The % operator can be used to determine if one number is evenly divisible by another. ( Java programing )

Answer #1

An
integer 'n' greater than 1 is prime if its only positive divisor is
1 or itself. For example, 2, 3, 5, and 7 are prime numbers, but 4,
6, 8, and 9 are not. Write a python program that defines a function
isPrime (number) with the following header: def isPrime (number):
that checks whether a number is prime or not. Use that function in
your main program to count the number of prime numbers that are
less than 5000....

/*
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

A Harshad number (or a Niven number) is a number that is evenly
divisible by the sum of its digits. An example is 18 (1+8=9, 18%9 =
0). Write a function called isHarshad(num) that takes an integer as
an argument and returns True if the number is a Harshad number and
False if it is not. Then, use this function to create a list of all
of the Harshad numbers in the first 500 natural numbers.

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.

Collapse
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.)

1) Write a C program to print the prime numbers from 1 to 100.
(A prime integer is any integer that can be divided evenly only by
itself and 1)
Requirement: Use an array to take the number from 1 to 100 and
another array to take the prime number.

Activity 6.6.
(a)
A positive integer that is greater than 11 and not
prime is called composite.
Write a technical definition for the concept of composite number
with a similar level of detail as in the “more complete” definition
of prime number.
Note.
A number is called prime if its only divisors are 1 and
itself.
This definition has some hidden parts: a more complete
definition would be as follows.
A number is called prime if
it is an integer,...

Write the following in C:
2. An integer is said to be prime if it is divisible by only 1
and itself. Write a function called prime() that takes in one
integer number, and returns 1 (true) if the number is prime and 0
(false) otherwise. Write a program to generate six random numbers
between 1 to 100 and calls function prime() on each one to
determine if it is prime or not.

Randomly generate an integer number in range [1, 999], (a) Check
if this number is even or odd, display message “[number] is an even
number” or “[number] is an odd number”. For example, if the number
is 10, display message “10 is an even number”. (b) Check if this
number is divisible by 7 and 11. Display message showing result (c)
Check if this number is divisible by 9 or 13. Display message
showing result (d) Check if this number...
