Write a c program to find out second smallest element of an unsorted array.
#include<stdio.h>int main(){
int a[50],size,i,j=0,small,secondsmall;
printf("Enter the size of the array: ");
scanf("%d",&size);
printf("Enter %d elements in to the array: ", size);
for(i=0;i<size;i++)
scanf("%d",&a[i]);
small=a[0];
for(i=1;i<size;i++){
if(small>a[i]){
small=a[i];
j = i;
}
}
secondsmall=a[size-j-1];
for(i=1;i<size;i++){
if(secondsmall > a[i] && j != i)
secondsmall =a[i];
}
printf("Second smallest: %d", secondsmall);
return 0;
}
Output:
Enter the size of the array: 5
Enter 5 elements in to the array: 5 7 3 2 6
Second smallest: 3
