"Is there any other way to find the right most digit of a number, other than getting the remainder of the number when divided by 10."

Question

Any arithmetic operator can be used but not %10..

Answer 1

//write the number to a string buffer and output the last character

#include <stdio.h>

int main(void)

{

long longIntNum = 123456;

int iStrLen;

char outbuff[255];

sprintf(outbuff,"%ld",longIntNum);

iStrLen = strlen(outbuff);

printf(">%s< : iStrLen = %d \n",outbuff,iStrLen);

printf(" THe last digit is %c \n",outbuff[iStrLen-1]);

}

Answer 2

Hi Satheesh,

 

Is there a specific programming language you are using or any particular reason why you want to do this? One way you could do this is to covert the number to a string and grab the last character and reconvert that to a number. For example, in Python you could do:

 

num = 2349

right_digit = int(str(num)[-1])
