C++ Programming Integer Sum troubles

[Noob Programmer]

my question is this.

A problem that lets the user enter any positive integer, but you do not have to check for this,
and then calculates the sum of the digits and displays this to user. For example, if user enters
14503, the outputted sum of the digits would be 13.

here us my program

#include <iostream>
int main(void)
{
int integer, sum=0;
while(integer)
{
sum += integer % 10;
integer /= 10;
}
cout << "The sum of the integers numbers is " <<sum;
return 0;
}

Well, you forgot to take number from user, but aside from that your program looks fine.

[Noob Programmer]

#include <iostream>
int main(void)

{
int Integer, Sum=0;
cout << "Enter an integer --> ";
cin >> Integer;
while(Integer>0)
{
Sum += Integer % 10;
Integer /= 10;
}
cout << "The sum of the integers numbers is " <<Sum;
return 0;
}

it tells me cout is undefined??

It is std::cout
