In this program, You will learn how to find second smallest number in an array in C++.

```
List is: 10 20 30 40 50 60 70 80
Second smallest number is:20
```

## Example: How to find the second smallest number in an array in C++.

```
#include<iostream>
using namespace std;
int main() {
int array[5], i, j;
int slar, temp;
cout << "Enter 5 numbers:";
for (i = 0; i < 5; i++) {
cin >> array[i];
}
for (i = 0; i < 5; i++) {
for (j = i + 1; j < 5; j++) {
if (array[i] > array[j]) {
temp = array[i];
array[i] = array[j];
array[j] = temp;
}
}
}
cout << "\nSecond smallest number is:" << array[1];
return 0;
}
```

#### Output:

```
Enter 5 numbers:10 40 50 20 30
Second smallest number is:20
```
