Write an integer and displays all its factors in increasing social club

Posted 09 November 2015 - 08:04 AM

(Find the factors of an integer) Write a program that reads an integer and displays
all its smallest factors in increasing order. For example, if the input integer is 120,
the output should be as follows: 2, 2, 2, 3, 5.

              #include <iostream> #include <iomanip> #include <cmath> #include <string>  using namespace std;    int main() { 	int integer = ii; 	int n;   	cout << "Enter an integer: "; 	cin >> integer;                  while (integer != 0)         { 	if (integer % ii == 0) 		n = two  		 	 	organization("pause"); 	return 0; }            

I'm having a difficult time figuring out how to pause the number apart. I know I demand to start with a 2 and practice some math. and probably the while loop should not equal 1.

The brute force method:

• Set the divisor to ii.
  
• Is the number divisible by the divisor? If and so, print the divisor, divide by the number by the divisor, and echo this pace
  
• Increment the divisor.
  
• Is the divisor less than or equal to the number? If so, go back to footstep ii. If not, you're finished.

If the number were 20:

twenty % 2 == 0, and so impress 2, set the number to xx/2 = ten
10 % ii == 0, and so impress 2, fix the number to ten/2 = 5
five % ii == 1, so increase divisor to 3
5 % three == two, and then increase divisor to 4
5 % 4 == one, so increment divisor to five
v % 5 == 0, then print five, increment divisor to half dozen
half dozen is not less than or equal to v, and so we're done.

Working and done correctly are two different things. Yous might want to postal service your solution so others tin can critique it. Judging by postal service #1 I'd expect there to be numerous improvements that could exist fabricated.

That'south what I got, although for some reason the loop does non stop

#include <iostream>  using namespace std;  int main() { 	int integer;; 	int divisor = 2;  	cout << "Enter an integer: "; 	cin >> integer;  	while (divisor != 1) 	{ 		if (integer % divisor == 0) 		{ 			cout << divisor; 			integer = integer / divisor; 		} 		else 			divisor++; 	}  	cout << "The factors of the integer are " << divisor << endl;  	arrangement("pause"); 	return 0; }            

Don't mind the afterwards ; on int integer;;. I was trying to notice how to edit the text just I can't discover the option to.

Of course the loop doesn't terminate - you don't have a condition that will brand divisor equal to 1. It starts at 2 and then either increases or stays at 2.
