C++ get each digit in int

Question

I have an integer:

int iNums = 12476;

And now I want to get each digit from iNums as integer. Something like:

foreach(iNum          


        

Answer 1

I don't know if this is faster or slower or worthless, but this would be an alternative:

int iNums = 12476;
string numString;
stringstream ss;
ss << iNums;
numString = ss.str();
for (int i = 0; i < numString.length(); i++) {
    int myInt = static_cast(numString[i] - '0'); // '0' = 48
    printf("%i-", myInt);
}

I point this out as iNums alludes to possibly being user input, and if the user input was a string in the first place you wouldn't need to go through the hassle of converting the int to a string.

(to_string could be used in c++11)
