Hello,

I have an integer value like 123. With that I want to add
theirselves, 1 + 2 + 3. value / 100 = 1 and value % 10 = 3. But how do
I get '2'? It's either 12 or 23, not only 2.
Thanks.

for a unspecified int you can do:


int addDigits(int i) {
int n=0;
while(i>0) {
n+=i%10;
i/=10;
}
return n;
}

std::cout << addDigits(23434);



output will be: 16
