# Find the second smallest number in an integer array in C++

This C++ program is able to find the **second smallest number in an integer array in C++** by using some suitable conditions. This problem is based on the concept of multi dimension array and also utilizes conditional statements. Following is a complete solution for the problem along with the source code.

## How to find the second smallest number in an integer array in C++

**Problem statement**

There is an array of size n with any value of elements in it. Find the second highest element in the array.

- Element values are entered by the user

**Problem approach**

- Declare an array of the required length.
- Store the array elements values.
- Find the required value using correct logic.
- Print the result on the screen.

**Source code**

Following program find the second smallest number in a given integer array.

/* C++ program to find second number number in array** ***give different sizes for array & the their values to get different result*** ** enter array values in the limit -2,147,483,648 to 2,147,483,647 only ** */ #include <iostream> using namespace std; int main() { int size; cout<<"Enter the size of array: "; cin>>size; int array[size]; // array declaration for(int i=0;i<size;i++) cin>>array[i]; // input array values int smallest=2147483647; // maximum integer values int secondsmall=2147483647; for(int i=0;i<size;i++){ // logic for smallest and second smallest value if(smallest>array[i]){ secondsmall=smallest; smallest=array[i]; } if(secondsmall>array[i]&& array[i]>smallest) secondsmall=array[i]; } cout<<"The second smallest number present in given array is "<<secondsmall; return 0; }

**Example outputs**

Enter the size of array: 5 Enter array elements: 65 313 131 89 32 The second smallest number present in given array is 65 Process returned 0 (0x0) execution time : 21.583 s Press any key to continue.

In this, an array of size 5 is declared and perform the operation and print the output successfully.

Enter the size of array: 8 Enter array elements: 53 23 436 467 253 15 95 68 The second smallest number present in given array is 23 Process returned 0 (0x0) execution time : 39.148 s Press any key to continue.

Here an array of size 8 is declared, accept values and do the requires operation.

**Program explanation**

- Accept size of array from user.
- Initialize an array using this size.
- Accept values for the same.
- Initialize two variables for storing the smallest and second smallest number.
- Use for loop to traverse through the array, then find smallest and second smallest values using conditional statements with suitable conditions.
- Print the required value on the screen.
