Finding the decimal digits of an integer

Recommended Posts

I can''t seem to find an easy way to extract a single decimal digit from an int. I would like to have a function that would return an int of the single digit I ask for. For instance if I had: int x = 5436; int digitToGet = 1; cout << getDigit(x, digitToGet); I would like to have a 6 print on the screen. BTW if I have the digits in the wrong order, and the first digit is the 5 I apologize. Any help would be appreciated.

Even better:

int x = 5436;
cout << x % 10 << endl; // print 6 to screen


You can use this property to obtain any number of digits from any number in any base:

// default to base 10
int GetDigits(int num, int digits, int base = 10)
{
int mod = 1;
while(digits)
{
mod *= base;
--digits;
}
return (num % mod);
}
