*Write a C program to find the second last digit of a number.*

For example,

Input123456Output5

**Steps**

- Let N be the input number.
- If N is a one-digit number, return -1.
- Set N = N / 10. This step removes the last digit of N.
- N % 10 gives us the last digit of N. Since we have already removed the last digit of N in the previous step, N % 10 is equal to the second last digit of the input number.
- Return N % 10.

#include <stdio.h> // function to return second last digit of N int second_last_digit(int N) { // remove last digit of N N = N / 10; // N % 10 gives the last digit of N // since we have already removed last digit of N // therefore, N % 10 gives us the second last digit of N return N % 10; } int main() { int N; printf("Enter a Number: "); scanf("%d", &N); printf("Second Last Digit of %d = %d", N, second_last_digit(N)); }

**Output**

```
Enter a Number: 1234567
Second Last Digit of 1234567 = 6
```
