I have a basic program that asks the user to enter a number and then I need to add just the odd numbers of 1 - what ever number the user entered. How would I write the code for this? Just the adding of the odd numbers I have rest of the code.

kwoti

what language are you writing in?
if it is c++ i just might be able to help you

hsmith1976

it is c++

kwoti

#include <iostream>
using namespace std;

int main()
{
cout << "enter your number" << endl;
int number = 0;
cin >> number;
int sum = 0;
int i = 1;
while(i <= number)
{
sum += i;
i += 2;
}

cout << sum << endl;
system("pause");
return 0;
}


Threw this toghether for ya, you could also use a for loop but a while loop works just as well

Thank you for the help I have been working on this for over an hour and couldn't come up with it.

Id go with a loop and a modulus. Itll reassure whatever you add will be odd.
If you dont understand, a quick google of that will explain it. Assuming you have basic math skills, it shouldnt be a problem.
Gluck.

Yeah a mod would look alot better.

Oh and make sure you put your "ints" at the beginning just for readability

Modulii are pretty easy. Just think of the result of a modulus as the remainder of a division operation. So 3 divided by 2 would = 1 mod 1 since 2 goes into 3 once with a remainder of 1.
