*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
```
