C Program to find the second smallest and largest number form and array :

This is an array program using c. In which we try to find the second smallest number and second largest number in array
First we have to create an array and input some element from user. then we will sort in ascending order or descending order.

ALGORITHM:-

step 1 : Start
step 2 : Enter size of array
step 3 : Enter element in the array
step 4 : Sort the array in ascending or descending order
step 5 : Now there is index[1] is the second smallest number and
step 6 : index[n-2] is the second largest number 
step 7 : Display the both (second smallest and largest) number
step 8 : Stop execution

PROGRAM CODE:-

#include<stdio.h>
#include<conio.h>

int main( )
{
     int a[50];
     int i, j, temp, n ;
     printf("Enter the size of array : \n");
     scanf("%d", &n);
     printf("Enter Element in array: \n");
     for(j = 0; j < n; j++)
     {
         scanf("%d", &a[j]);
     }
     //Sorting array using bubble sorting in ascending order
     for(j = 0; j < n; j++)
     {
        for(i = j + 1; i < n; i++)
        {
            if(a[j] > a[i])
            {
                temp = a[j];
                a[j] = a[i];
                a[i] = temp;
            }
        }       
     }
     printf("The second smallest number is: %d\n", a[1]);
     printf("The second largest  number is: %d", a[n-2]);

     getch();
 }

OUTPUT:-

Enter the length of the array: 5
Enter element of the array: 
5
1
9
5
4

The second smallest number is: 4
The second largest  number is: 5
