C Program to Get a Digit of Any Position of a Number

This C program finds the digit of specified position of a number. The numbering starts from 0. The least significant digit of a number is 0-th digit. For example 0th digit of 2341238 is 8 and 3-rd digit is 1.

#include <stdio.h>
#include <math.h>

/*Function to return the digit of n-th position of num. Position starts from 0*/
int getdigit(int num, int n)
{
    int r, t1, t2;

    t1 = pow(10, n+1);
    r = num % t1;

    if (n > 0)
    {
        t2 = pow(10, n);
        r = r / t2;
    }

    return r;
}

void main()
{
    int num = 0, pos;

    printf("Enter an integer: ");
    scanf("%d", &num);

    printf("Enter a position: ");
    scanf("%d", &pos);

    printf("%dth digit of %d is %d.\n", pos, num, getdigit(num, pos));
}

Output: (Position starts from 0).
Enter an integer: 345672
Enter a position: 3
3th digit of 345672 is 5.
