Find the 2nd smallest element in an Array using C++ #shorts #cplusplus

In this C++ program, we demonstrate how to find the second smallest element in an array of integers. The program takes user input for the number of elements in the array (n) and the array itself. It then employs a loop to iterate through the array and efficiently determine the second smallest element.

Here's how the program works:
1. The user is prompted to enter the number of elements (n) in the array.

2. The user is asked to input the array elements one by one.

3. The `second_small` function is defined to find the second smallest element in the array. It uses two variables, `small` and `s_small`, to keep track of the smallest and second smallest elements found so far. It iterates through the array and updates these variables as necessary.

4. The `main` function initializes a vector to store the array elements and calls the `second_small` function to find the second smallest element.

5. Finally, the program prints the second smallest element to the console.
